Can anyone point me to a good tutorial on how I can best make melted cake art for a cake I am doing? I am thinking about making some sort of chocolate fencing surrounding a cake and I thought it would be easy but when I attempted it before, the chocolate melted before I could get it all on the cake! UGH!

If I understand correctly, you're making a fence from chocolate or candy melts?

Are you doing the fence in sections or trying to make a whole long fence? I would suggest making sections of fencing about 3-4" long and then place them on the cake.
