I had been looking for a good way to mail my magnets, mirrors, or buttons, especially when I'm sending out just one. I think the bubble mailers that I have are too big and bulky for just one. I've sent out some in just a regular white envelope for letters, but I don't think that is ideal. Then I found these:
Making my own mailers is the perfect solution. I can make something that's just the right size and will look more interesting than a plain envelope! My first one I did from a grocery store paper bag. I'll have to lug out the sewing machine to try sewing it instead of taping it. I really like the results though. Sorry I don't have a picture to show you, I mailed it out super fast!
