This is a Snail Mail Folder that I made, using some Kraft card stock paper, washi tape, stickers, and a couple brads with twine. I made sure that I cut it to size to fit into a clear cello bag for mailing.
When it is opened, there are two pockets on the left to put paper ephemera, stickers, journal cards, tags, etc. On the right is just one large pocket holding the letter. (You can see this folder letter finally being mailed off in this post: Blog Post )
Keep all of your scrapbooking paper scraps...this project uses quite a few.
