Three Rolls of Duct Tape

On a whim, I decided to paint 3 rolls of duct tape.  I gained confidence with each one.  It's pretty obvious that the painting order was blue, pink and purple.  I'm happy with the purple one, especially the highlights. The blue one is pretty wonky.  The drawing wasn't too bad, but it sure did not work when I painted it!!

Also, I'm not sure how to represent the writing on the inside of the roll. Hmmmmm.
