I'm doing a couple of practice cakes for a May wedding.
I'll try to attach a picture-it will be tiny, but hopefully some of you will have seen it. It was in The Knot last summer.
I have not had good results with fondant, but the cake she wants has brush embroidery.
Here are my questions:
How thick is the bc layer under the fondant?
Do I let it crust before laying on the fondant?
How about chocopan?
I've read that some you you find chocopan easier to work with when mixed with fondant-what's the ratio you use?
Also same question...do I let the bc crust?
Any other tips will be GREATLY appreciated 
!
Can't seem to add the pic...
Hi, the buttercream shouldn't be too thick. I put the crumbcoat and then roll out my fondant and then cover the cake. In Sugarshack's DVD, she puts the crumbcoated cake in the freezer until she finish rolling the fondant. Then take the cake out and then cover it with fondant.
HTH.
You can do brush embroidery on crusting buttercream, it doesn't have to be fondant.

Okay, I think I got it...and I'm going to do two practice cakes, one fondant/chocopan, and one crusting bc. Any difference to embroidery on the bc-other than a lighter touch? And do you use corn syrup to thin the bc for painting? I can use bc, right, not just RI.
Again, thanks for all the replies! 
You can use buttercream as long as it is a crusting bc. Make sure it is set before you do the embroidery work on it. The bc will need to be thinned a little, but not too much, you don't want it to run. Make sure you work with one area at time though, you don't want it setting on you.
I can't help you with the fondant part because I have never worked with fondant, other than the Wilton practice cake for class and a fondant bow that I made one time!
