Most purses and wallets start off as a single sheet of duct tape.

To begin, you must know how wide you want your project to be, so that you can make your sheet a little wider. Line up and stick two pieces, sticky side up.

This particular sheet of duct tape was going to be used for a purse, so we made it long enough to fold into one.

Keep adding more and more strips of tape, all sticky side up, until you have the length you want.

Leaving half the width of the top and bottom tape free, cover the sticky side (evenly) with face-down tape.

Fold in the two sticky ends to make the top and bottom neat. 

Cut the two length sides evenly.

You now have a beautiful sheet of duct tape to use.
