This is perfect timing!! I was just going to ask these same questions. I had my second class today for Wilton Course 3. I made the MMF and added gum-tex to the mmf for the flowers. I got part way through a petal and it started to dry...terribly so. I did manage to get my cake covered with the MMF without gum-tex and that worked beautifully. I know it has to be possible to make the flowers and all the other decorations with the MMF, but mine keeps cracking. My instructor said that Wilton fondant is kind of hard to work with once it starts to set, but if you knead it you should be able to roll and stretch it. Well, the MMF doesn't stretch, it crumbles apart. When I was making the MMf earlier I did get it to a stage that it felt like really thick silly putty. It was easy to work with, stretched nicely and wasn't so sticky I couldn't do anything with it. Of course, the lack of stickyness could have to do with all the Crisco I had rubbed into my hands, and the counter, and the rolling pin, and the roll/cut mat, etc...lol. But I thought it was too thin so I added a little more powdered sugar. Was that my mistake? Is MMF supposed to be stretchy and easy to work with? I really really want to use just MMF on my cakes due to taste and cost. But, I'm starting to think that if it'll crack everytime I try to make a decoration, I might use the Wilton Fondant to do decorations and such and just the MMF to cover the cake. My instructor said maybe adding some Karo syrup or glycerin to the mixture before the final step of powdered sugar might help with elasticity. What do you guys think? Also, what should I do if I do make it too dry? Can I add a few drops of water and knead it in to make it workable or would I have to start all over again? Also, I've read that people add gum-text to their MMF and some add gumpaste...which would be better? Thank you thank you thank you in advance for your help!!
