Mixing Pluffy and Premo

Bought a set of Pluffy yesterday using my 40% off Michaels coupon. It felt nice but was very hard to work with--too soft. I made a kind of cool Phoenix-like creature, but it sagged and fell apart. Wire inside didn't help much either. It's now a greenish grayish blob.

So next question was could it be mixed with Premo? Found answer on Internet today, so I'm pleased.

According to craftygoat.com and zigzag.co.nz, Pluffy mixed with Premo is the same as the discontinued product called Studio Sculpey.

I also saw that baked Pluffy should float, so one could try to create something like a very simple and flat-bottomed boat out of pure Pluffy.
