For many years I've used rather simple method of brushing on a coating of rubber cement to the back of the pattern and then apply it directly to the wood surface. After a few minutes the material is ready for cutting. Removal of the pattern only involves peeling it off and using either an eraser or fingertips to rub off any residual cement. Compared to spray adhesive, the rubber cement is relatively cheap. And, I always use clear packaging tape atop the pattern to help "lubricate" the cutting.
Does anyone else use this method?
