I used to just spray glue the pattern onto the wood directly. I'm not sure if I used too much glue, but I always had a hell of a time getting the pattern off, even with mineral spirits. Even if the pattern came off, I still had sticky adhesive on the wood that had to be sanded or rubbed off. There were times with fine fretwork on plywood that I would either break pieces, or sand right through the top ply trying to get the glue off. Now, I use the green frog tape because that's what I can get in bulk around here. I usually try to get the 2" or 3" wide stuff, but cover the entire top surface of my wood piece. Its night and day difference for me. The pattern pulls up easily, and if any pieces rip and stay, it doesn't take much to get them. I also tape around the edges to keep my plywood stacks together while cutting. No more fighting with paper stuck to small fragile patterns, no more sticky glue adhesive to try to sand off the finished product. I've thought about trying the shelf liner others here talk about, but haven't gotten around to it yet.
