How much gumtex will I add to a batch of MMF to get this look ?? To make the fondant stiff. And if for some reason I do not have gumtex (I can't remember if I have any or not) is there anything else I can I use to get this same effect ??

I have heard you can knead in 1 teaspoon of gumtex to about a baseball clump of fondant. Also have heard you can use the same amount of Fixodent denture powder to that amount of fondant if the items are not to be eaten.
