Step 1: Gather Materials
Step 2: Build the frame
Now, take the end of the string and feed it through one straw, then feed it through the other straw. It should make a big square. Cut the string and tie the ends together. You want it to be taut, but not bending the straws.
Step 3: Make the skin
Once you have your square, cut notches out of the corners of the square. The notches should expose the corners of the frame as shown in the picture. Then, fold the flaps of plastic over and tape them down to fasten them to the frame. Do this on all four sides. The plastic should be taut, but not bending the frame.
