Hi, i was wondering if anyone can give me a few tips on covering a 3 tier cake. It has to be be chocolate covered. I know I can always use chocolate buttercream icing but I'm not even sure on how much I will need. I will be doing a 14, 12 and 10. Any other suggestions? Thanks

Here's a link to Wilton's cake making charts:

If you look up your cake pan sizes, there's info on how much frosting you'll need...
