Hi Cyn.. Yep. I have used them
In fact that is the same cake that I made for my FIL's 70th birthday. I don't recommend you use them in 90+ degree weather with no available air conditioning like I did that day. How I ever got chocolate on my back will forever remain a mystery. smileys/smile.gif
They are really pretty easy to use. I did not experience any cracking. It's just kind of stressful making sure that you did it right, although on my part that could have been stress with having to do the whole birthday party by myself in the heat.
Now I have several sheets left so if you would like I'll send you some before you go to the expense of buying them and deciding that you don't like them.
Send me a PM with your address and I will get them out to you if you would like.
