Panel Play was inspired by a Lonnie Rossi fabric Panel. We just could not cut it up. The pattern includes directions for using a preprinted 24" repeat panel or you can create your own panel out of a collection. The finishing touch is the quilting you do. You can free style around your designs with metallic threads or use decorative stitches to dress up a solid fabric. Lenghtening is the key and those directions are included in the pattern. We recommend 50/50 blend sweatshirts with set in sleeves for best results. The pattern includes directions for fitting the sweatshirt, lenghtening and lining the jacket. There is no pattern sizing. The pattern is written for all sizes. Sizing is determined by the sweatshirt size that you purchase.
