I made MMF last night and it was pretty soft, I thought I would let it sit over night but it is still kind of soft. Should I knead in some more sugar or can I just knead in some gum tex and model it? I need to make a Snoopy tonight.

My last batch was soft too but I just adjust as needed. I did some numbers to put on a cake and put in some tyclose and rolled it out on cornstarch. That worked great. Usually I roll it out on a little shortening, but since it was soft I didn't. Not sure if I helped alot but you may have to try a little and see what works best.
