Cracked Glass is one of my favourite techniques, and it's easy to do, though a bit time consuming!
1-stamp your image.
2-colour your image, if necesary.
3-cover your image with Versamark.
4-pour on the Ultra-Thick Embossing Powder (SU Glassy Glaze).
5-heat with a heat gun.
6-repeat steps 3,4 and 5 TWO MORE times...(total of 3 times).
7-place image in freezer for 2 minutes.
8-remove from freezer and IMMEDIATELY bend the paper. It will crack.
9-rub the image in Chocolate Chip ink, making sure to get ink in the cracks then wipe off the excess with a Kleenex.
See, easy peasy!
