I am making 3D bears and blocks, should I use 50/50 fondant & gumpaste or all of one?
I've used straight fondant for my 3D figures but if it makes you feel more secure use a 50/50 paste.
I use 50/50, it dries harder and um... the name is escaping me now... gum glue? I can't remember...a little pea size piece of gumpaste mixed with a tablespoon or two of water. when it dissolves, you can use it to glue your pieces together and they won't fall apart. I tried water with my first figure and the arms and legs kept falling off!
I live in a very humid area, and I use straight gumpaste for 3-D work. Figures made with fondant or even 50-50 won't dry properly - they sag or "melt". I usually dry my items in a food dehydrator, too. It is frustrating to end up with misshapen figures after so much work, so I use gumpaste or chocolate (or candy) clay.
I agree with ibmoser for the same reasons, you can make your own gumpaste by adding tylose to fondant, works great
I would use a mix for figures. It dries quicker and is more stable. but if you have lots of time, straight fondant works too!
All the figures I have made were fondant mixed with gum tex.
