I finished my circle cutout cake.. let the circles dry, and the didnt lose their shape at all! I also used meringue powder and water to stick them, perfect again

It came out pretty great.. I still had a problem getting really crisp edges.. which I'm not really sure how to improve on.. so tips on that would be awesome.. and my mmf was reaaaaaaaaly sticky and kind of hard to work with.. but the person I made it for absolutely loved it. This is only the 3rd fondant cake I've made.. so any advice.. would be great. but I posted a pic under my pictures so you can all see how your previous advice paid off.

thanks again!
