I having trouble working with my fondant. Not homemade, store bought. Duff. Its HOT. Even thought I have the air cranked up my fondant is soooo soft I'm having trouble working with it. Won't hold its shape. I've already added tylose powder. I'm not sure if I should add more. I have to have 2 cakes done for Saturday and this isn't going well.I'm assuming its the heat of my hands and I keep putting it down and walking away but I'm never going to get it done.
