The only time I use a pin is when I get a splinter; and that doesn't always work as well as a #11 blade.
I prefer to use wax paper and 3M77 spray. The sprayed glue goes directly on the plans (copied plans), which are then covered with wax paper. A small amount of 3M77 is then sprayed on the fuse/spare/tail-feathers/etc... and positioned on top of the wax paper.
When done, the excess glue sands off easily, and the plans have a subtle tackiness that allow them to be rolled up without the need of a rubber band to secure them.
Works for me
