I just learned to make mmf and I love it am not sure if I can do royal icing embroidery on it does any one know if I can or not all responses are very much appreciated

There should be no problem. Roll out a small test square and do a design. The only problem would be caused by using a lot of Crisco, either in the MMF or when you rolled out the fondant. (I never used Crisco, either in the MMF or when I rolled it out.) I look forward to the finished cake, it should be spectacular.

Of course it will definitely be ok. I love brush embroidery. Good luck.
