Was experimenting making a tiarra. A trick that I tried that worked - after I made the tiarra I put it under my food dehydrator to dry out. I put it under there for 3 hours took it out and peeled off the wax paper and THANK GOODNESS no breakage - I piped on 3 layers of royal icing.
Wow - this is so detailed. Great work. Thanks for sharing your technique (I'll have to try that!).
