So i just finished mixing a batch of gumpaste and its totally too dry. It's wilton dry mix and i've used it before, but no matter how much it told me to knead it, it was still too dry. I couldn't even knead in the full 1/3 cup powdered sugar like it said. Its jus tkeeps getting harder and harder...HELP?

You could try using some shortening on your hands. This will help it become more pliable.

Hmmm, that's weird, I usually love the Wilton gumpaste because it is so true to the directions compared to other brands I've tried. I would try adding a little water, few drops at a time, and keep kneading....
