I keep a few old paperbacks with my craft supplies, because the book pages make such a great background. All I used otherwise were moo cards (some of my own business cards, and some of the older small ones), some stamps, a few summery magazine pages, and LOTS of washi tape for some stripeitude. I coated them all with a light coat of Mod Podge, because I was afraid they’d fall apart in the mail. (They didn’t, so it worked!) We always send cards to wish friends and family happiness in the winter, but why not wish everyone a happy summer? It’s my favorite time of the year! I made my required postcards, but also a few extras for my out of town friends, and sending an unexpected surprise in the mail is one of my favorite things to do.
