This may sound silly (I'm a newbie) but which is the best method to prepare gumpaste for making flowers or figures
1.buy a ready made tub of gum paste
2.make gum paste from scratch
or
3. use fondant and sprinkle some cmc powder ( not sure of the ratio)

Appreciate your comments

If you have never used it before, I'd say go with the premade, it will give you a feel for the texture of it. You can also add a gum to fondant but when I do that I don't measure, I just dump and kneed it in then if it doesn't feel how I want it to I add some more.
