As per a suggestion by Anita
, I'm experimenting with the mix of 50% sculpey ultralight and 50% premo, today. I've got a new little chibi in the oven curing as I type this.
The material felt the same as plain ultralight as far as weight and softness was concerned. The texture while sculpting was sticky instead of powdery, and the blending was super easy and smooth and no additional mediums were needed to remove seams.
The next test will be when it comes out, I'll state the texture and ability to work with other mediums for coloring.
Thanks to Anita for the suggestion. :o)
