Hi, I saw a video tutorial on Nik the Booksmith you tube channel about a specimen pouch folio thingie and I loved the design so much, I made one myself. You can find Nik's video here. I call it a snail mail envelope. I used the inside cardboard of a wrapping paper roll for the cover of my envelope. The inside has four pockets/tuck spots to put in all kinds of ephemera, little notes stickers and other goodies. I love how this envelope turned out. Thanks for stopping by my blog. Hugs, Henriëtte.
