I am making 2 pig heads for a bday party on Friday. I am awful at pricing- what would you recommend charging? I don't want to overcharge, but I tend to undercharge. I am also making a cross cake for a 7 yr old boy's 1st communion. His mother said 'make it white and blue'...hmmm, I've never done a communion cake before and don't want to screw this up, but I'm at a total loss for ideas!
