There are just so many ways to apply glitter, this is just one... "glitter 'n tape technique". If you haven't tried it yet, you just gotta! So simple, and it really sticks. Some tapes work better than others, but almost any clear tape will work. Heck, you don't even need clear tape if you are using colored glitter. Whatever you choose to use, be prepared to sparkle!
Just a note about the music... since I'm making a Christmas card, you'd think I'd have Holiday music. But come on, how perfect is a song with the chorus "Don't you know, everywhere I go, I got the shimmerin' light on me." How could I pass that one up? And glitter and rock 'n roll go hand in hand, right?
