I could be wrong but to me it looks like they are real teacups with decorated cupcakes inside.
This isn't an old thread, but a cc'er posted on a thread to help us out with some instructions. She directed us to her photos of some really nice hand painted tea cups. Maybe this is the person you are looking for.
Hi Laurel, I'm not sure if this helps but here is an overview of what I found:
I got a tutorial from Kim Morrison (PA) through a magazine article she did... I used it and although not easy to do... it can be done.... but I used mexican paste instead of fondant.. my tea cup was bigger though... maybe with smaller ones you CAN use fondant...
I made a flower paste tea cup not so long back, and i used an actual teacup to be the mold (the inside of the cup) Once it had dried it was beautiful and stood on its own, i filled it with flower paste carnations. The ones in the picture look like mini cakes covered with fondant and turned upside down.
Thanks everyone..There is some really good intructional ones out there!! I'll give it a go if the customer decides to order them.
