I printed out the instructions for this technique from Splitcoast a while back and finally got the time to give it a try! It is the Cracked Glass technique and very easy to do!
I used the Time Well Spent stamp set and colored it in using various colors of purple (my favorite color!) I'm sorry, I forgot to write down which colors they were, but it all colors and paper are Stampin' Up! I used my cuttlebug embossing folder to make the Happy Birthday background. I had a hard time at first cracking the "glass" because I didn't realize just how much you have to bend the paper, so there is the crack across the middle that I didn't really want, but it is still OK. This is a great technique! I sent this to my upline for her Birthday card and she really liked it!
