I have a carnival mask shaped cake to make for a friend in about a month. I've got the carving somewhat figured out, but I'm not too sure how to cover it with fondant. I may not be able to cover it in one piece, since he asked for the eyes to be cut out of the cake (to give it a real mask look) but I fear that may affect the clean look of the finished cake. I've considered cutting out separate pieces, connecting them, then filling any gaps with dyed royal icing, but I don't know how I'll cover that up.

Any suggestions are welcome. Thanks in advance!

i would dig a nice hole where the the eye holes go but not too deep -- cover that with black fondant then place the big piece of fondant (that will cover the entire cake/mask) quickly fit it and then cut out the eye hole -- i'm sure i'd use a template 

so all you see is nothing in there -- just a dark opening -- nobody home kwim

Thanks! I'll test it out sometime this weekend.
