Some rug hookers have been contacting me after reading my recent article in Rug Hooking Magazine on Dyeing Palette Wool (follow this link to purchase a copy of the magazine if you don't own a subscription). I mention in the article as an aside the pebbling stitch that I developed in order to hook zones of color and value in my portraits. They want to know how to pebble stitch.
So here is a link to some of my past blog instructions on this stitch. Hope it helps. Click HERE to learn how to pebble stitch.
