My friend, Pam, over at Lost Art, has some cute pictures of envelopes she made. I was inspired a few years ago to make my own and have really enjoyed it. I use scrapbook paper (if using regular and not two-sided, then you’ll need to make a liner), and old calendars. I use envelope templates that I purchased from Paper Source. Although there are free ones available online, I like these plastic ones. They have faired well through many, many uses.
Here’s some that I’ve made. I hope you will try this easy craft. It’s a nice way to brighten someone’s day when they receive this in their mailbox!
