A VSN challenge at splitcoaststampers.com really pretty easy here is an easy tutorial to follow.
But basically stamp an image cover with several coats of ep or UTEE it works best in my opinion. then pop in freezer for a few minutes then take out and bend till it cracks like you want it to.
here is a close up of the cracking.
lion - stamp oasis
background - stampendous
words - printworks
hope to do a few more challenges but time is not on my side this weekend. grrr oh well next time
