I use 3M Super 77 spray adhesive to attach my patterns to my workpiece. I spray it on heavily so as to prevent the pattern from lifting up while cutting delicate areas.
I thought that removing the pattern was going to be a major pain in the neck. Fortunately, my dad has a solution that he has been using for years: a heat gun. His is a Milwaukee model that blows 50oF - 1000oF hot air.
You have to work in small (4 x 4 inch) sections and keep the gun moving so you don't scorch the pattern or the workpiece. After about 5 seconds of heat, the pattern can be easily lifted - even from delicate areas. You want to heat just enough to weaken the glue so the pattern will lift up. Overheating will just result in more glue residue left on the workpiece.
Once the pattern is off, I sand off any remaining glue residue with 100 grit sandpaper.
BTW, a heat gun has many other uses that will justify its purchase. These include stripping paint, removing floor tiles, and thawing ice encrusted locks.
