I just cut the plan into pieces and use my 4 year olds supply of Elmer's Glue sticks. Cheap and effective. It will also adhere wood to wood for multiples like wing ribs. It's a good idea to remove the paper and separate the parts as soon as they're cut to avoid problems.

I always make a two additional copies of the plans at kinkos as well. One to cut, one to build on and one to keep pristine.
