I think this is a really cute cake, but I can't give you an estimate since I am only a hobby baker.
Everything, everything is gumpaste? Like the blocks, key rings, carriage, frog, & everything else? If so, how in the world did you do those itty bitty key rings?!
Yes it is all gumpaste. I just rolled out the gum paste and used an exacto knife to cut them outand make a hole for the ring. let em dry then roll out a small piece of gumpaste(make sure its thin enough to gently slide the keys on and let it dry.
wow, patience of a saint. Okay, so when someone asks what should they charge, I base it of the cake design as well. So for me to give my opinion on pricing, I also judge the cake. So, do you REALLY want me to asnwer the question honestly? Cause I will be honest. Also, is this a 4" high cake or a regular sheet cake with no fillings and a sheet of cake?
