This is what I use, not because I am cheap (I am?), but because it works good for me.
I buy cheap tan masking tape. Whenever it is on sale I get a bunch. I cover the top of the project. If it is stacked I go all around the project. Toothpicks hold it together. I then spray the pattern very heavy and put it on the taped up wood now. I don't worry about the wood grain because I know where it is before I cover it. Then drill and cut. The first whiff of hot or smoke I put clear packing tape over the pattern. I very, very seldom have a pattern come off the project. If I do I slap down a piece of scotch tape or hold the pattern down with a tapered popsicle stick. After cutting I soak it in MS for a minute and never have problems getting it off after that.
