I'm going to make an attempt at MMF, do you decorate it just like you would regular fondant??
Also, any suggestions on how to attach an edible image to MMF?
I have only ever worked with MMF, so yes, use it just like regular fondant. Here's a tip...I just started adding 1/2 cup Crisco and it makes it so much easier to work with. 1/2 cup Crisco in the bowl. Then put 1/2 the sugar in the bowl. Add melted marshmallows. Mix with dough hook. Then add sugar until you get the desired consistency.
Also, to attach an edible image...I have done it once or twice...you can put a little crisco on it to make it sticky or use water. Whatever you do, use it sparingly so you don't mess up the image.
Thanks again for another helpful hint!!
