Twill tape is a necessity of sewing. Miki directed me to a website and I ordered. I thought they would come in normal-sized spools of tape, but arrived in massive quantities ! I hung them on the existing nails in my sewing area, and only yesterday realized how many repeat shapes live in that corner. The painting is an old one of mine, one of several box-themed works at that time. The white cardboard shapes are my daily-used pattern 'blocks'. The plaster casts are a weakness of mine....I have a foot as well.
