Step 1: Stabilize Box
Step 2: Smooth Surface With Paper
Step 3: Fabric Wrap
Grab a piece of spare fabric from an old shirt, pillowcase, whatever! Cut it about 2" bigger than your box on all 4 sides. Place the fabric face down on a table, and lay the box on top with the paper-covered side facing the fabric. Use fast drying contact cement on one edge of the back of the box and fold the fabric over. Let dry, and repeat on the side opposite the first, stretching the fabric slightly to make it smooth.
Step 4: Fold Corners
To make the corners look nice, fold the fabric over itself at a 45 degree angle. Note that this is a great way to make the bed too!
Step 5: Secure Corners
Add a few extra drops of contact cement to each corner and press down to secure.
Step 6: Hang
I like to use binder clips to hang this from hooks on the wall because they double as a great way to hold pens or other items. They're also super easy to move so that you don't have to be perfect when placing the hooks.
