For one who asked about - Window technique...I first learned how to from a F&P episode a long time ago......there may be a video iPod it somewhere on YouTube. But basically - you draw whatever pattern onto the fusible, rough cut around the outside, and on the inside of the design cut out leaving only about 1/2" of fusible product on the inside of that pencil line of the design. Then fuse onto fabric and fine cut out design. This allows the fusing, but eliminates the stiffness and/or bulk. Hope I explained clearly...
