I need some serious help with square cakes and fondant. Every time i do a square cake with fondant it doesn't turn out the best, the corners are never perfect like i want them, i have all the tools just not able to get it right. If anyone has any ideas what to do or any videos on how it's done, that would be great. PLEASE HELP

There is a video by Lorainne McKay (aine2) that shows how to cover a square cake with fondant. Here's a link to her website and you can search for the video:

here are a few hints. Roll out the fondnat a little thicker than usual and don't roll it out super large, just enough to cover the cake and a lil over.

Place on the cake and let it rest for a minute and then work from the top down.

my best advice would be to get sugarshack's fondant dvd. I'll never do a cake the same again, it is fantastic!!!
