I have never had any luck using fondant mats with MP. No matter what I do, the base finds its way under the mat and the pattern is not clear at all. Sometimes the mat has even disappeared into the base and I have to pry it out after it hardened. I tried fondant mats with MP at least 10 times with no luck, so I gave up. However, fondant mats work beautifully for me in CP. I have done individual molds, but mostly I line loaf molds with the mat and it works great.
