Strawberries at the Workshop

This is another journal painting done on the Arches Cover paper. When I made this journal and tied off the thread, which I had added in the middle of the book, I left the tail a little longer than usual. The thread is waxed, and it left some resist marks on the paper.It shows up on the bottom and left strawberries. Have I discovered a new painting technique? Pressing waxed thread onto watercolor paper for a resist design? Or using it as masking? Hmmm - veins in leaves, texture in wood, tendrils, stamens . . .? I'm absolutely sure this is not a big (or new) discovery in the art world, but I'm going to play around with it.
