This is a couched sketch. When the FIVE had a recent playdate, I was rummaging through some of Charlene's goodies when I spotted this skein of thin cotton (yarn?). It was like crochet thread but had intermittent wrappings of black thread - very yummy. I thought of doing a sketch using this material/yarn and couching it down. Must say I like it.
In the spirit of explaining the process. I did the sketch with the sewing machine and white thread then used the stitches as a guide to lay down the yarn/thread and couched it with black sewing thread.
