Some fabric glue (optional)
Paint pallet (optional)
Step 1: Painting the Box
Then put on a first coat of whatever color you like. If it doesn't cover as well as you like give it a second coat like I did here
Paint the inside and outside as you please
Step 2: Decorating!
Step 3: Finishing Up
Paint the inside.
Put stuffing on the bottom for cushioning if you like and that's it! It looks like a brand new box :)
