To start I stamped an image on a piece of cardstock. Here I chose Indian Corn Blue on Daisy White Cardstock. Trim cardstock to size desired and then press your Versa-Mark or other clear embossing inkpad all over your entire piece of cardstock. Next cover with clear embossing powder and heat with heat gun until powder has melted. Immediately recover with another layer of embossing powder and heat.* Repeat with at least four layers of embossing powder. This is more or less a preference and as you play you'll find how many layers you prefer. As soon as you can comfortably handle your heavily embossed piece of cardstock walk yourself to the kitchen and carefully place your piece of art in the freezer. Wait at least 15 minutes and then remove your embossed cardstock and proceed to bend and twist carefully until you have the amount of cracks and breaks you desire. Warning, people very well may look at you quite strangely when you remove your piece of art from atop the ice cream tub!
*IF you are having trouble getting the embossing powder to stick to the warm melted layer of embossing you can also run it over your Versa-Mark pad again.
I DID try this technique using another medium as well. It is more time consuming, but if you don't have embossing supplies and tools this may just work for you! I stamped an image as above and after cutting to size I scissor distressed the edges to give them a raised edge and then filled the cardstock with "Liquid Glass". Let the Liquid Glass dry overnight and then proceed to the freezer for about half an hour before cracking and twisting to your heart's content. It is obviously a longer process, but it did give a thicker "glass" and more defined cracks and breaks.
Either way a very fun and sweet addition to any card, scrap layout, or bit of altered art! Try it soon and let me know how it turns out! I'm off to make some cards for my cracked bits of fun!
