First put a little crisco on your hands and knead it. Sometimes my gumpaste is tacky until I knead it. If it's really bad, you can add a little powdered sugar. Just a little. What's your weather like, if it's really hot and humid that could be affecting the paste.
With that said, you don't want to add too much powdered sugar or you'll lose your elasticity, if you have a little tylose powder or CMC you can add that to help.
Sorry it's so hard to help without being there to actually see it.
I also like the Wilton gumpaste..it is my fav thing from Wilton. Like the other's said...add a little crisco to the fingers and knead it in...it's great to work with once you do that!...straight out of the bag is impossible...
I did the roses on myjust posted future DIL's cake using the Wilton Gumpaste
