If I am scrolling one piece of wood, I just spray the pattern with adhesive and apply the pattern to the wood. If I am stack scrolling, I cover the wood with blue painters tape and then attach the pattern with spray adhesive. I always keep an original hard copy on file and also on my computer and I also take a photo of the work and add to a "catalog" I have put together using a ring binder. I use the binder as a catalog of what I have made to sell. I also have a pattern catalog of potential scroll work.
