I am going to do a tree stump cake and want to be able to carve into the fondant .. I am thinking of using modeling chocolate though.. thinking I will get a better look with it.. my questions is... have you ever combined modeling chocolate and fondant together?? I am wondering what that would be like.. I want the sturdiness of the fondant but the "carvablilty" of the modeling chocolate...

I mix fondant and modeling chocolate all the time - - it works great.

Yep works great. I like modeling chocolate but in the summer it's harder to work with so I mix it with fondant. Also if my modeling choc is dry, adding a little fondant gives me better work ability. I think it's a great combo.
