The background on this piece is surgical tape that I got for a $1.00 at an estate sale. I like using masking tape usually. Surgical tape is thicker and the paint does not seem to adhere as well but the price was right and I thought I would try it again. I painted the background several colors and then stenciled the blue. You also see washi tape and the collage materials I found in an exploration book for a $1.00.
