Last year, I created a slide mailer "card/picture frame" for my kids grandma. It was fun to create and I really like the outcome of the project. To create, glue or decoupage scrapbooking paper to a slide mailer. Print, cut to size and add pictures and embellishements to the slide sections of the mailer. Add glass slides to the mailer and adhere using glue. Add embelishments and more pictures to the mailer. Add tape (electrical or fancy) to the edge of the mailer for a bound look.
