i've carved a few cakes before, i'd like to know from others who have done cake busts, did you use a styrofoam head or cake? if you used cake, did you overexagerate the features on the face alot if you covered in fondant. i'm looking for some advice from cc's who have created busts. what about internal structural support? what worked best for you? i'm septical but willing to attempt the elvis bust so any information is greatly appreciated! thanks!!
