Most of us photocopy the pattern and apply the photocopy directly to the wood surface using spray adhesives. I use 3m spray adhesive as it is relatively inexpensive. I spray the back of the photocopy and wait about 30seconds to allow the glue to tack up a bit.
I then apply directly to my pre-sanded (to 220 grit) wood surface. I then cover the entire pattern with clear packing tape. This ensures the pattern wil not lift, and helps lubricate the saw blade to avoid burning.
Once I'm through cutting my project i use mineral spirits in a spray bottle and thoroughly cover the pieces/project. Let it set for a few minutes and the pattern and tape will lift right off. If there is any residue left behind I spritz it one more time and wipe off with an old t-shirt as it is lint free.
I then dip my finished project in either pure lemon oil or danish oil, blow off or wipe off excess and let dry.
That's how I do it now and for the past 10-12 years. Hope it helps.
I do basically the same thing but in a different order and one additional item.
Once the wood is prepared, I put on shelf paper which when done cutting, comes right off with very little if any residue, i.e., all that is require is very light sanding, no more than normal to get rid of the cutting marks. I get 50 sq ft (20" x 30') for around $10.00 at Lowes/Home Depot. (Steve Good uses 8-1/2" x 11" sheets that he get from Sloan's --- shelf paper is 2 to 3 times cheaper depending on the quanty and even without shipping).
I then cover everything with packing tape and finally, the pattern goes on top. (I also use 3M Super 77 spray adhesive). I put the pattern on top of the tape because I have had the tape trapping the saw dust and making thing hard to see, especially walnut (but that is what I've found, others may not have had that problem).
I finish with Watco Oil (danish oil).
