The blocks I am doing are 15". Glad you like it. Very easy to do. You take a pieceof organza, and put a mesh stabilizer under it and hoop them. Then, you do your embroidery design. Unhoop, and either cut around the embroidery design, or use a heat tool, that is what I did, then, place the embroideries on your block where you want them, and use monofilament thread to stitch them on. That's all there is to it....My designs I am using are from Jenny Haskins. She offers the heat tool there. I bought mine at the Paducah Quilt Show a couple of years ago, in Paducah, Ky.
