I am doing my first large square cake with fondant soon, and would love any advice that anyone has on making this a success. I am doing a 16" square, I have the large Ateco mat 24"x40" and hope that this will make it a snap. I would appreciate any words of wisdom that anyone has. Thanks in advance.
Also, has anyone worked with FondX before? I really like the taste and texture, not to mention the price is awesome!, but am unfamiliar with the texture and what is the ease of use.
You can either put the fondant straight on the cake from the mat (as long as the mat doesn't have a mild pattern that will show) or you can make sure there is some pwd sugar on the mat (so it moves easily) and then drape it over the rolling pin as you transfer it.
FondX is really nice, I think its a little softer than other fondants, so its easier to work with but can also pull into holes on your cake a tiny bit easier as well, just be careful for that. I personally prefer it. It tastes great too!
When I roll out a large piece of fondant (like covering a 16" round base) I use clear plastic vinyl cut in two. I bought a yard of it at Wal Mart and cut it in two and rolled out on one half, covered it with the other half, flip the whole thing over, remove the top sheet of vinyl and then I use the other half to lay my fondant over my tier! Doing this ensures you get the right side on top instead of underneath.

I think also ensuring you get the right thickness and size is essential, especially if the fondant is slightly softer than most fondants.
If its too thin it will tear more easily and if you roll it too much bigger than your cake size the weight will cause it too stretch! 
Its taken me a while to get fondant right but it does come, I also use a smooth large (thin) cutting board to slide underneath the fondant, with powdered sugar on, then slide on to the cake, I find it easier using a board as it doesn't bend when I'm transferring it to the cake.
I think its trying methods which suit you best. Good Luck!

Thank you for all the advice. I have worked with fondant quite a bit before, just not on such a large scale. I will keep my fingers crossed and be extra careful. I have noticed that this FondX is a lot softer than others I have used, and have to take that into consideration when rolling out. Thanks again. BTW, Jan I was in Bath, UK last year, what a beautiful place, can't wait to return.
