I cut the backing and batting larger than my finished art piece and layer them and pin to the design wall. Then, I make a sketch by just looking at the photo. When I like the general sketch, I trace over my pencil lines with a Sharpie pen. If I want to keep it this size, then I use this for a pattern. If I want to make it larger, I trace it to transparency film and use my overhead projector. I would then have to trace it to a larger size paper. Now that I have the pattern sheet to the size I want, I place it on a light box. At this point, some of my pieces will have Wonder-Under applied and some will not. I place the Wonder-Under (lite) over the pattern and trace. I then iron it to the fabric and cut it out. Then, I pin to the wall and keep tweaking until I have the "first draft" of my art piece. Everything is pinned in place.
