I am fairly new at selling cakes and I have a wedding cake that I am making with a sugarpaste topper on it that I made. Could anyone give a ballpark amount I should charge just for the topper. calla lilies (3) with leaves. Would be much appreciated.

I would really charge for your time and skill for a topper. Don't forget your ingredient costs either! So let's say they took you 4 hours to make and the ingredients (gumpaste or whatever) cost you $10, I would charge $10 + 4 x $X (whtever you feel you should earn per hour - I never go below $10 per hour for such skilled work! Hope that helps.
