Making 50th Anniversary Invitations - Card Stock won't work in printer
A good scrapbooking adhesive tape, like Elmer's CraftBond Permanent Tape (http://www.elmers.com/product/detail/E4006) will provide strong adhesion without the mess and wrinkles of glue. I recently used it to stick regular paper into a sketchbook (with thick art paper pages), and it was great. No wrinkles, no mess, and very sticky.
