I'm looking at this mat http://www.cakesupplies4u.com/Products/Fat-Daddios-Fondant-Work-Mat__SFM-2436.aspx
Fat Daddio's Fondant Work Mat, on the CakeSupplies 4 U site, just in case the above link doesn't work.

Is this a good mat? I've heard of some being able to use this with rolling fondant/gumpaste and NOT need any shortening/sugar to keep it from sticking.

Thanks for your info!

Yep I like mine! I do still have to use a little dusting of pwd sugar but nothing like if I used a regular countertop.
