Take the hooks off the suction cups and paint the suction cups on the backside. I did flat white spray paint. I chose to do this for a contrast, since they are clear.
Step 3: Sewing and cutting shirt.
Sew the arm holes shut and sew across the shirt. See below. Then cut the shirt apart. You will have the two arm pieces and the center and sleeves of shirt as scraps.
Step 4: Attaching suction cups and preparing arms.
I found that dropping the suction cups in the arm and pinning on the reverse side was easiest. Working my way up from smallest to largest. I then turned them right side out. Next, I took 10 pipe cleaners and wrapped plastic bag around it, like a giant q-tip. I then inserted into the tip of the arm. Do the same for the other arm. This will make the first 11 inches bendable, you can curl it or make it wavy.
Step 5: Put on and enjoy!
Using a rubber band on each arm, I secured it on my upper arm. I had to have someone help me on the other arm to secure it. Also, I stuffed the arms a little, to have less fabric sagging. I engaged in some tomfoolery with the arms. I will be sewing them onto the sleeves of another t- shirt, letting its sleeve fall over the arms, that way I will be able to put them on with no assistance. And engage in more tomfoolery.
