I used the 45 craft spray from 3m a few years ago. You want a better idea with no cummy wood to sand....try this.....
Buy clear shelf contact paper at walmart in rolls, sand your wood, cut piece to fit on wood urface. Take your pattern and copy it onto full size packing labels, then stick that on top of the contact paper and when your done cutting just peel it all off and wood is clean. I have been doing this for years and it works well. If you have small patterns, just put more than one on the shipping label and cut that down to size after printing pattern out.
