Take a ticket stub, plane ticket or whatever to kinkos, have them blow it up, print it on fabric transfer material to make a pillow. This would be so fun for big trips or things done as a couple (honeymoon tix, first concert together, etc)
Monogrammed Hand Sanitizer/Soap Bottles. The best part of these is that they are so affordable and practical. They are also completely customizable. You could really put anything on the transparency and they could be used for so many things...birthdays, home decor, teachers, for new parents, frequent guests, etc.
