This was my 2nd cake and had a ton of scraps! Trial and Error on sizes. Ended up using a 40+ yr old Pyrex bowl set that I found in a box from my mom's house. (Shape is a little different then more current) But I started with muffin/jumbo cupcake pans. Like I said trial and error. The Wilton pan was just too small for the amount of servings I needed. I was pleased with it and it was the first time I ever made anything out of gumpaste.
