I was wondering if anyone had any ideas on how to make fondant more stiff like gumpaste to work with it but to where it won't harden up like gumpaste but maintain a softer texture when eating

Try mixing half fondant half  gumpaste

Or add some gum tex or gum tragacanth to fondant

You can add 3/4 tsp tylose to 1 pound of fondant and it will stiffen up but not get as stiff as gumpaste.

Well I've heard about doing that but doesn't it dry harder like gum paste? I'm trying to find a way to make fondant stiff while shaping but to where it will still dry softer to where people can bite into it and it melt in their mouth unlike gum paste which gets too hard for my taste

Not if you use half of each

I have that exact same question right now!

I have this cake that has a lot of flowers on the side of the cake that need to be made before hand because there are so many! But I still need them to be edible, I was going to make them out of just fondant but I can't shape them so maybe 50/50 gumpaste/fondant?? I only have access to a Michaels & no time to order any of gum ingredients online if I had to. Any suggestions appreciated!
