Use Spray adhesive. If you think it's going to be messy, it's not. Just lay a piece of newspaper on the floor or do it in your garbage can.

I work with vellum a lot (My business is making printing on vellum perfect) and I've tried about everything made for vellum. You can see just about anything else (even the newest Glue Dots for Vellum) or it's too expensive to make it practical(xyron)

BRAND? I prefer Creative Imaginations 'Scrappers Spray' but really I've used many others and they akk do a good job. (Helmar V2 is odorless, or 3M, Krylon, Elmers to name a few which are readily available everywhere.)
