How do you float the tiers on a slant angle when making a whimsy cake?

Check this out... it's a great tutorial for making whimsical slanted cakes:

Thanks. I've already seen this. I'm not that bold yet to try carving. I'm talking about maybe slanted foam or some kind of cake seperator that's already cut on an angle. Anyone know where to buy? Instructions?

Use the buttercream to create the whimsy effect. Spread the buttercream on a slope between the two (or three) cakes on each layer. Continue as you normally would. I use extra dowels when make these cakes. I will try to post pictures (can't promise I will get around to it) but I will not be able to do that before Monday or Tuesday of next week. Hope that helps!
