My favorite medium lately is Plaid’s crackle medium. It’s super easy to use – you just paint it on, allow it to dry then paint over it. Shortly thereafter, you have crackle! Jen from My Crafty Friend Jen tried the crackle medium herself and made this awesome frame for a scrapbook layout. I LOVE the pink FolkArt paint peeking out from under the white. The crackle effect is so cool, and you need to check out everything she did to plus out her project here.
