Tired of cluttered cabinets and wasted space, especially under your kitchen sink? Imagine turning ordinary cereal boxes into a brilliant, multi-functional organizer. This DIY project is not just a craft; it’s a smart solution to elevate your home organization, proving that practicality can be beautiful and budget-friendly. Get ready to transform your under-sink area with an upcycled creation that’s as effective as it is easy to make.

If you’re anything like me, a home lacking efficient storage can be a constant source of frustration. This frustration often peaks in the kitchen, a hub for countless cleaning supplies, dishcloths, and various odds and ends. The space under the sink, in particular, is notorious for becoming a disorganized abyss. Many cabinets, like mine, lack built-in shelves, leaving a vast, untapped vertical expanse that quickly devolves into a messy pile.
I grew weary of the chaos beneath my sink and was determined to find a clever, inexpensive fix. The result? A remarkably simple yet highly effective hanging organizer made from items I already had on hand. This project isn’t just about tidying up; it’s about reclaiming valuable space and injecting a sense of calm into your daily routine.

With just a couple of empty cereal boxes, some decorative paper, and reliable adhesive strips, you can construct a customized, multi-pocket organizer that attaches directly to your cabinet door. This isn’t just easy and affordable; it’s also incredibly quick to complete, making it the perfect weekend project. In just a short time, you’ll have a dedicated spot for those stray washcloths, spray bottles, and cleaning sponges that used to clutter your cabinet floor. Let’s dive in and transform your kitchen!

Why Upcycle Cereal Boxes for Kitchen Storage?
Upcycling is more than just a trend; it’s a mindful approach to consumption and creativity. Choosing to transform everyday items like cereal boxes into functional home decor offers numerous benefits. Firstly, it’s incredibly eco-friendly, diverting waste from landfills and giving cardboard a second life. Instead of tossing those empty boxes, you’re reimagining their potential and reducing your environmental footprint. Secondly, it’s wonderfully cost-effective. Why spend money on expensive plastic organizers when you can create a customized solution with materials you already have? This project requires minimal investment, making it accessible to everyone.
Beyond the practical advantages, there’s immense satisfaction in crafting something useful with your own hands. This DIY cabinet organizer isn’t just a container; it’s a testament to your ingenuity and a unique piece tailored to your specific needs. It’s a chance to add a personal touch to your home decor, selecting papers and colors that complement your kitchen’s aesthetic. By embracing upcycling, you’re not only decluttering your physical space but also fostering a more sustainable and creative mindset.
Supplies for Your Upcycled Organizer
Gathering all your materials before you begin is key to a smooth and enjoyable crafting experience. Most of these items are likely already in your home or easily acquired. Here’s what you’ll need to create your fantastic new cabinet organizer:
- Thick paper (or wrapping paper): This will be used to cover the exterior of your organizer, giving it a polished and attractive finish. Choose a color or pattern that brightens your space!
- Paper (for the inside of the organizer): A contrasting or lighter shade works best here to line the interior, covering up the original cereal box print.
- 2x Cereal Boxes: The stars of our show! Ideally, choose two boxes of similar size for a cohesive look, though a slightly smaller one for the front pocket can also work.
- Double-sided tape: Essential for securing paper neatly and ensuring flat, smooth surfaces.
- Self-adhesive Velcro strips: These provide a strong, removable hold for mounting your organizer inside the cabinet.
- Glue: A good all-purpose craft glue will work well for various adhering tasks.
- Ruler: For accurate measurements and straight lines, crucial for a neat finish.
- Pencil: To mark your cutting and gluing lines.
- Cutter (craft knife or box cutter): For precise, clean cuts through the cardboard. Scissors can also work, but a cutter typically offers more control for straight edges.

How to Make Your DIY Under-Sink Cabinet Organizer: Step-by-Step Guide
Ready to turn those humble cereal boxes into an organizational masterpiece? Follow these detailed steps to create your custom storage solution:
Step 1: Gather Your Essentials
Begin by laying out all your supplies in a clear workspace. Having everything within reach will make the process much smoother. While it’s ideal to use two cereal boxes of similar dimensions for a balanced look, don’t worry if one is slightly smaller. A smaller box can be ingeniously adapted to create the front pocket, adding a unique asymmetrical touch to your organizer. Visualizing the final product helps in making initial adjustments.
Step 2: Mark Your First Cut Line
Take your first cereal box – this will form the prominent front slot of your organizer. Using your trusty pencil and ruler, carefully draw a straight line horizontally across all four sides of the box. This line will dictate the height of this front compartment. I found that drawing the line just over halfway up the box worked perfectly for holding standard cleaning supplies, but feel free to adjust this measurement to suit the specific items you plan to store. Precision here ensures a neat final product.

Step 3: Make the Initial Cut for the Front Pocket
Now, it’s time to cut! Using your craft knife or box cutter, carefully cut along the line you just drew on all four sides of the cereal box. The goal is to remove the top portion, leaving you with an open-top box. A craft knife is generally recommended for achieving impeccably straight and clean lines, which is crucial for a professional-looking finish. If you’re using scissors, take your time and follow the marked lines as accurately as possible to avoid jagged edges.

Step 4: Prepare the Back Compartment Box
Repeat the cutting process for your second cereal box, which will form the taller back compartment of the organizer. This box needs to be notably taller than the first one. The extra height is essential because we’ll be cutting a decorative and functional notch into it later. Refer to the provided image for a visual guide on the ideal proportional difference between the two boxes. This will create a tiered effect, offering varied storage depths.

Step 5: Begin Personalizing with Decorative Paper
Now for the fun part: customization! Choose your decorative paper – I opted for a calming blue that offers a clean aesthetic, but your organizer can reflect any shade or pattern that inspires you. Cut a sheet of this paper to match the width of the taller box. You don’t need to cover the entire box just yet; focus on the area that will be visible. The paper should be long enough to extend behind where the smaller box will eventually sit. Apply glue evenly to the back of the paper and adhere it smoothly to the taller box, ensuring no bubbles or wrinkles.

Step 6: Prepare to Attach the Front Pocket
Next, we’ll attach the smaller box, creating the multi-tiered effect. Apply strong adhesive strips to the back of the smaller box, focusing on the edges and center for maximum grip. To ensure perfect alignment and prevent overshooting, I highly recommend using a pencil to lightly trace a guiding line on the taller box where the top edge of the smaller box will meet. This small step makes a big difference in achieving a professional and well-aligned appearance for your organizer.

Step 7: Secure the Front Pocket to the Back
Carefully mount the smaller box onto the taller, decorated box. Align the edges as precisely as possible, making sure it adheres firmly to the adhesive strips. The goal is to create the illusion of a single, unified storage unit with distinct pockets. Take your time during this step; proper alignment will contribute significantly to the overall aesthetic and stability of your organizer.

Step 8: Design the Functional Notch
Now for the distinctive notch in the taller box, which adds both visual interest and practical functionality. Using your pencil and ruler, draw a neat rectangle on the upper front portion of the taller box. Pay close attention to keeping the lines straight and ensuring the margins from the sides are even. I typically draw mine about 1.5 inches in from the side edges, leaving the top edge open. This creates a convenient opening for easily grabbing taller items.

Step 9: Cut Out the Notch
With your rectangle perfectly outlined, grab your craft knife once more. Carefully cut along the drawn lines to create your “window” or notch. Precision is key here to achieve clean edges. For an even more refined and custom look, if you’re comfortable with your craft knife skills, consider gently rounding the corners of the rectangle. This small detail can significantly enhance the organizer’s aesthetic appeal, making it look less like a cereal box and more like a designer piece. The final shape should resemble a neatly cut-out opening, as shown in the accompanying image.

Step 10: Complete the Exterior Covering
Now, it’s time to fully cover the smaller box and the remaining exposed parts of the taller box with your primary decorative paper. Using double-sided adhesive tape works wonderfully here, as it helps the paper lie completely flat and prevents curling at the edges, ensuring a smooth, seamless finish. You have two options for covering: either wrap a single large sheet of paper around the entire structure (excluding the back, which won’t be visible) or cut individual panels for each side and glue them on one by one. I found the wrapping method quicker and resulted in fewer seams. Don’t worry about the back of the organizer, as it will be flush against the cabinet door. Your organizer should now look largely complete from the front and sides.



Step 11: Line the Interior for a Clean Finish
Don’t forget the inside! The bare cereal box cardboard can look a bit unsightly. To give your organizer a truly finished and appealing look, line the interior back of both compartments. Select a contrasting or lighter shade of paper than your exterior covering; this often creates a pleasing visual pop and a clean backdrop for your stored items. Again, adhesive tape is your best friend here for achieving smooth, flat interior surfaces. Carefully cut and adhere the paper to fully conceal the original box print.


Step 12: Admire Your Handiwork!
Congratulations! At this point, you have successfully constructed your very own, custom-designed cabinet organizer. Take a moment to appreciate your creative efforts. The primary construction and aesthetic detailing are complete. All that remains now is the final and satisfying step of mounting your new storage solution securely inside your chosen kitchen cabinet door. You’re just one step away from a tidier, more functional space.

Step 13: Mount Your Organizer to the Cabinet Door
For mounting your organizer, self-adhesive Velcro strips are an excellent choice due to their strong hold and ease of repositioning if needed. First, attach one side of the Velcro strips to the back of your newly made organizer. Then, to ensure perfect placement on your cabinet door, consider lightly tracing the organizer’s outline onto the door with a pencil. This tracing will serve as your precise guide for attaching the corresponding Velcro strips to the cabinet door. Once aligned, press firmly to secure the organizer in place. For heavier items, consider using more strips or even heavier-duty mounting tape.




Step 14: Enjoy Your Organized Space!
And there you have it! A completely customized, highly functional, and aesthetically pleasing kitchen organizer, perfectly designed to maximize space in your once-cramped cabinets. Step back and admire the transformation. You’ve taken simple, discarded items and given them a new purpose, solving a common household storage dilemma with creativity and minimal expense. Now, the previously overlooked space behind your cabinet door is a practical haven for your essentials.

What to Store in Your New Under-Sink Organizer?
This versatile organizer is ideal for a variety of lighter items, helping you keep your cleaning supplies and kitchen essentials neatly categorized and easily accessible. The multiple pockets mean there’s a designated spot for everything, eliminating clutter and saving you time. Consider it the perfect home for:
- New sponges and scrub brushes: Keep them dry and within reach, ready for your next cleaning session.
- Dishcloths and rags: Fold them neatly into the pockets to prevent them from getting lost in a pile.
- Small spray bottles: Store your favorite all-purpose cleaner or glass cleaner upright.
- Garbage bags: A roll of bags fits perfectly in one of the deeper pockets.
- Dish soap and hand soap refills: Keep backups handy without taking up counter space.
- Rubber gloves: Tucked away for easy access when tackling tough jobs.
Its utility isn’t limited to under the sink! If you’re looking for extra storage in your pantry, it can hold lighter pantry items like spice packets, small snack bags, or grocery lists. Mounted on the side of your fridge, it becomes a convenient drop-zone for mail, pens, or important bills. The possibilities are endless!

Important Tip: Remember that this organizer is made from cardboard. It’s crucial to store only dry objects in it. Exposing it to wet sponges or bottles with leaking liquids will quickly degrade the material and shorten its lifespan. Always ensure items are dry before placing them in the organizer to maintain its integrity.
Organize Kitchen Cabinets Without Shelves
The absence of shelves in under-sink cabinets is a common design flaw that often leads to inefficient storage and frustrating clutter. This DIY cereal box organizer provides a brilliant, budget-friendly remedy. Instead of investing in expensive, often ill-fitting shelf inserts, you can create custom vertical storage that perfectly suits your needs and space.

For those with an abundance of cleaning supplies or kitchen gadgets, consider making multiple organizers. These can be configured side-by-side or stacked (with adequate support) to create an even more comprehensive storage system. They’re an ingenious way to give old boxes a new, valuable purpose. This project empowers you to take control of your storage, turning chaotic spaces into models of efficiency without breaking the bank.

Should you decide to store slightly heavier objects, such as multiple full spray bottles, it’s wise to reinforce the mounting. Apply additional adhesive Velcro strips to the back of the organizer and the cabinet door, or opt for a more robust mounting medium like small command hooks (if the material can support them). This extra precaution ensures your organizer remains securely in place, even when fully loaded. No longer will you dread opening the cabinet door to confront a jumbled mess. You’ll know exactly where everything is, making cleaning and daily chores a breeze. Go forth and organize your kitchen cabinets to your heart’s content, one upcycled box at a time!

Frequently Asked Questions About DIY Cabinet Organizers
Can I use different types of cardboard boxes for this project?
Absolutely! While cereal boxes are ideal due to their consistent size and ease of cutting, you can experiment with other cardboard boxes like cracker boxes, pasta boxes, or even lightweight shipping boxes. Just ensure the cardboard isn’t too flimsy and that the boxes are clean and dry. You might need to adjust the dimensions to fit your chosen boxes, but the fundamental steps remain the same.
How can I make my organizer more durable or waterproof?
For added durability and a degree of moisture resistance, you can cover your finished organizer with contact paper or clear adhesive vinyl instead of regular decorative paper. Another option is to seal it with a clear, water-resistant spray sealant (like Mod Podge spray). While this won’t make it fully waterproof, it will offer better protection against splashes and humidity, extending its lifespan, especially in areas like under the sink.
What if my cabinet door isn’t perfectly flat or has an uneven surface?
If your cabinet door has raised panels or an uneven surface, standard adhesive strips might not get full contact. In such cases, consider using strong adhesive hooks (like Command hooks) and attaching loops to your organizer, or use small, thin wooden shims to create a flat surface for the Velcro strips. Alternatively, you might attach small, lightweight screws if your cabinet door can safely accommodate them (though this is a more permanent solution).
Can children participate in making this DIY organizer?
This is a fantastic project for older children (with adult supervision, especially when using a craft knife). Younger children can help with non-cutting tasks like choosing and applying decorative paper, gluing, and lining the interior. It’s a great way to introduce them to upcycling, organization, and basic crafting skills, fostering creativity and a sense of accomplishment.
