Box slipcover tutorial

This tutorial will show you the steps to cover any box you have in your house.

In my case I chose a strawberry box. Now, this wasn’t the best choice.

As you can see the sides of the box don’t go all the way up and the corners aren’t straight. I’m considering at this stage taping some cardboard to the box so the sides go all the way up and the cover sits nicely up.


  • Cotton fabric. The amount will depend on how big your box is
  • Trim of your choice. I think that a pom pom trim adds some cuteness to the plain cover.
  • Box – cardboard, wooden, plastic


First of all you need to measure your box. You need to measure the height, the width and the length.

Now double the height size.

Then add 1/2 in to each measurement.

For instance my box measures:

  • Height: 3 in
  • Width: 7 3/4 in
  • Length: 11 3/4 in

I doubled the height so it is 6 in.

Now I added 1/2 in to each

  • Height: 6 1/2 in
  • Width: 8 1/4 in
  • Length: 12 1/4 in


  • Bottom panel:  width x length rectangle (12 1/4 in x 8 1/4 in)
  • 2 short side panels:  width x height (8 1/4 in x 6 1/2 in)
  • 2 long side panels: length x height (12 1/4 in x 6 1/2 in)

Note: You could just use one panel for the bottom and one for the sides. In that case you need to work out the length of the box by measuring it all around from corner to corner and then adding 1/2 in to it.

Pin 3 of the side panels alternating short and long sides and leave one side open.


Do a rolled hem as per picture.

Stitch with a zig zag or decorative stitch.

Now it’s time to add the trim to the side panel. I placed mine at about 1 1/2 in from the bottom but you will need to look at your box size and decide where it looks more pleasant.

Stitch the trim.

Now pin both sides and stitch.

Pin side panels to bottom making sure the corners match the side seams.

Turn inside out. I pressed the fold to make the slipcover sit more upright. If the sides of your box go all the way up it won’t be  necessary to press the fold.

Depending on the box design you may be able to stack them up. Or maybe you can also do nesting sizes.
