2 fat quarters per box
some interfacing or batting
Step 1: Cut out your fabric. I only show the pieces for the small box because all of the steps are exactly the same, just different sizes.
For the small square box:
Outside fabric: 15"x15"
Lining fabric: 14 7/8"x14 7/8"
For the rectangular boxes:
Outside fabric: 17"x21"
Lining fabric: 16 7/8"x20 7/8"
For the square box: cut out 4 1/2"x4 1/2" squares from each corner.
For the tall rectangular box: cut out 5"x5" squares from each corner.
For the short rectangular box: cut out 3.5"x3.5" squares from each corner.
Once you've sewn the two edges, fold the fabric to match up the other two sides. Pin and sew.
Smoosh it into the lining fabric box like shown.
Pin around the top. Start with the corners and then pull two neighboring corners slightly before pinning the center edges.
Turn the fabrics right side out.
You can see that the box is not terribly boxy at this point. Iron the creases using steam or starch to stiffen them up.
Step 7: Here's a nifty trick I came up with. This step is optional, but I discovered that it helps keep the boxes even more boxy. See how the sides bow out?
Take each corner and pinch it. Sew a 1/4" seam 1/2" long. Make sure to backstitch several times so that it is secure.
Now your sides won't bow out!
All done. Now you can fill them up with fabric scraps, small toys, binkies, chunky jewelry, thread...etc. The short rectangular one works great for ribbon and it totally beats the plastic bag I kept them in before!
