I am attempting to make a gumpaste teacup. I read on here to put shortening on the outside of a cup and cover with gumpaste then let it dry. I attempted this but when I tried to take it off it just cracks. 
Am I supposed to take it off before it dries? What am I doing wrong? Does anyone have anymore tips for me? HAPPY THANKSGIVING!
This is a thread discussing how to make teacups. Using cornstarch seems to be the answer, not shortening and then put your gumpaste inside the cup.
I would think your gumpaste would stick to the shortening which would cause the breaking of the cup when trying to remove it, but it wouldn't stick to the cornstarch.

HTH... 
I wish I'd have found the instructions for making a teacup last spring. I tried everything, then ended up using the mini wonder pan (the small princess version that does 4 cakes). I only filled the pan with enough batter to make a teacup size cake, then just covered that with fondant. It was just the shape I needed, and suprisingly, without having to trim the cake itself, it stood up perfectly without tipping over; though I did push down slightly on it once I applied the fondant.
I have a few teacups and saucers in my pics. I used one of my own teacups and greased the inside with crisco, I cut a circle of gumpaste wider than the rim of the cup and let it droop down into the cup. What I do is spin the gumpaste in the cup every once in a while so it doesnt get stuck, then once it dries, I slowly push it up all around the rim til it releases, I do the same thing with the saucers, I keep spinning the gumpaste around every so often until it is finally dry and its not stuck to the plate.
