I read something recently wherein the author recommended that one use a red ball point to do the tracing with. I wasn't really sure why except that maybe that would allow one to know which lines had already been traced.
Have you ever used graphite paper? I like it better than carbon paper.
On occasion, I will simply glue the pattern to the wood and go from there. When I do, I use the glue in the aerosol can and just spray the back of the pattern lightly.
I've left plenty of room for people to improve on my response...
