I think the Cracked Glass technique is quite striking, but I don't use it too often. That's the joy of Fancy-Schmancy camps. I can play with stuff I usually put off and leave in the To-Do pile. Then it gets me psyched to do it more!
This card is one we did at camp. To make it happen, you have to have Ultra Thick Embossing Enamel (UTEE), which Stampin' Up! calls Glassy Glaze. Stamp your image, put VersaMark ink all over, add the Glassy Glaze, and then go emboss. Repeat until you have three (or 4) layers of glaze. You'll know you're done because the glaze will all the sudden be really really really smooth (and glassy!). Then pop it in the freezer for about 10 minutes. No kidding. The actual freezer. Once it's frozen, take your image out and crack it. No rules here, just crack it 'til you like it.
If it's still sort of gooey, stick it back in the freezer. It's gotta crack. Once you have all the cracks you want, sponge a little ink over the top (we used Creamy Caramel) and wiggle it into the cracks. Just brings 'em out a little more.
Have a great time with this project! Here's what I used: Friends 24-7, Chocolate Chip Corduroy Buttons, Key Tag Punch (retiring), Bella Rose Designer Series Paper (retiring), Kiwi Kiss, Creamy Caramel, and Chocolate Chip ink and paper.
