you get rid of the corn starch on the fondant after rolling it out and cutting it?
Most of it will brush away with a natural bristle pastry brush. Some times I use clear vanilla or vodka and airbrush it to get rid of the rest. the vanilla and the vodka evaporate quickly enough as to not damage with the fondant.
Hope it helps
a little wipe down with shortening will do it.
use a ball of the fondant that you topped the cake with and rub lightly not only get the flour off but smooths and puts a shine to your cake
If you can get one of those small hand-held clothes steamers, they work really great. They're pretty inexpensive too. Just lightly wipe off any heavily coated spots of cornstarch and then steam the entire cake. Make sure you keep the cake moving on the turn table and don't leave the steam on any portion of the cake too long; it could melt some of your delicate decorations.
Thank you for all the great ideas!
