How to make custom fabric storage cubes of any size and using any fabric. Simple, inexpensive step-by-step tutorial for fabric storage boxes.

Well, my boys’ room makeover is rolling right along! As I shared last week, I’ve taken on the challenge of transforming my older son’s bedroom into a shared room for both of my boys as part of the One Room Challenge.

The challenge part? I only have six weeks to finish the whole room makeover!

This week has been all about building DIY closet shelves to create as much storage space as possible in their one small closet.

The whole closet system isn’t finished yet, but I do have one fun project to share today: custom DIY fabric storage cubes.

A major part of the closet plan is a section of built-in cubbies to hold clothes and shoes and those cubbies were in need of some stylish storage bins.

After doing a bit of online shopping, I realized that there were plenty of inexpensive fabric storage bins out there.

Unfortunately, I couldn’t find any that would work in the boys’ room. Everything was either too small, too expensive, or too ugly.

I’m putting a lot of work into this closet and I want it to look good by golly!

So I did what I always do when I can’t find what I want – I decided to make it myself!

And I am so glad I did, because these turned out gorgeous! They are absolutely perfect and I can’t wait to see them in the closet.

Plus they were inexpensive and you can make absolutely any size fabric cube using any fabric you want!

spray adhesive
craft knife and cutting mat
Square ruler (optional)

How to make DIY fabric cubes

Ok, so the easiest thing to do would be to simply cover some cardboard boxes with your fabric (much like I did here), but that doesn’t always work as well when you need a specific size box.

I couldn’t find any boxes the right size, so I started from scratch.

You need to cut five pieces of foam board for each box. My boxes are exactly 13” x 13”.

In order for your cubes to perfectly square, you need to take into account the overlap of the foam board at the corners.

To make a 13” x 13” box you need two 13” x 13” squares (for the front and back), two 12.5” x 13” squares (for the sides), and one 12.5” x 12.5” square (for the bottom).

You can easily cut the foam board using a craft knife and cutting mat.

If you have a square ruler, it makes it much easier to keep all of the edges nice and straight.

I also chose to cut out a hand hold to make it easier to use.

I simply cut a pattern from card stock and then traced it onto the front piece, centered, one inch from the top.

Then I carefully cut it out with the craft knife. This way, I can trace the same shape quickly onto each box I make.

Once all of the pieces are cut, simply use duct tape to attach each of the pieces at the seams.

The front and back pieces will slightly overlap the side pieces.

You could possibly use a hot glue gun for this instead of duct tape, but I prefer to avoid hot glue whenever possible. (I’m not the only one who manages to always burn myself and ends up with a million glue strings everywhere am I?)

I also used some duct tape to reinforce the handhold. Just make sure to keep your duct tape as smooth as possible – big wrinkles can show through the fabric.

Ok so it may not look like much yet, but adding beautiful fabric is like magic.

I chose this fun shibori print which I got for a steal at Joann Fabrics with a 40% off coupon.

I was able to make two large cubes using just a yard and a half of fabric.

I cut my fabric in half lengthwise so I had two strips of fabric that were 22” x 54”.

Then I wrapped each piece of fabric around one of my DIY boxes. I used spray adhesive to attach the fabric and it worked perfectly.

The last step was to use my craft knife to carefully cut several flaps in the hole for the handhold and then wrap the fabric flaps around the hole.

How gorgeous is that! You would absolutely never guess that this high-end storage cube was actually made out of foam board and duct tape.

These boxes are very sturdy – sturdy enough I feel comfortable letting my kids use them and that’s saying something.

And I love that you can make them the exact size you need with your absolute favorite fabric for a custom look.

*Update – I’ve finished the DIY built-in closet shelves for these boxes and it looks amazing!

I love the custom fit and the shelves were actually much easier to build than I imagined.

And I’ve also since built wooden storage cubes from cedar planks if you prefer the look of wood.
