You need two different colors of tape
LOTS OF PATIENCE
Step 2: The Woven Panel
First take a strip of tape seven or eight roll widths long. Lay tape face down. Take another strip of the opposite color tape and lay it at right angles on the other strip of tape, color side down, with half an inch of tape extending over the top (see picture) and a two tape widths extending down the other side. Now lay another eight roll width long strip of the first color down on top of the second piece of tape that was lain down alongside of the first long strip. Now do the same thing but in reverse. Take a short piece and go under the first long piece and over the second long piece. Continue in this fashion until you have six short pieces woven into the longer ones. Try to keep all the pieces of tape as close to flush as you can. After this take two long pieces of tape and cover the back of the panel you just made. cut off any excess on the sides. Fold over the excess on the top of panel. Leave the excess on the bottom long, we will use it later.
Step 3: The Inside Panel
Lay color side down six of the short strips side by side. Lay two long strips down on top of them. Wrap the top and bottom excess over and cut off the excess on the sides.
