I picked up some acrylic circles from cakethings . com and tried them out for the 1st time yesterday. It was just a cake I was bringing to a frien's birthday so gluten free guests could have something yummy. For the first time ever, I had a guy come up and say, "I have never seen such sharp 90 degree angles on a cake."
What I did:
1: level, torte, crumb coat, let sit over night to settle
2: remove any bulges
3: frost the top, nice and level and let crust
