Try this, believe me it works-sand wood an wipe clean-spray wood with 3m adhesive spray-lay pattern on top-I go.over the patterns making sure all wrinkles an bubbles are out. you can start drilling holes immediatly, then start cutting your pattern. I have tried several adhesives but none are good as 3m, you will have no trouble with pattern coming loose if you make sure wood is completly covered. When cutting is finished I sand an use a small torch to burn fuzzies off. I never use tape unless to hold wood together on narrow cuts. next I take mineral spirits an paint over pattern. In just a few seconds the pattern will lift off all in one piece. As quick as you get pattern off paint the wood surface with mineral spirits then wipe it down with a cloth. If you will do this under a light an tilt the wood you can tell if you have all the glue off. Don't wait to take glue off. DO NOT take pattern off ahead of using torch, mineral spirits will ignite. (I know from experience)
