i use sculpey III cause its the most readily available one, and its cheaper than the FIMO i seen. also, i love that i can buy the 30 pack sampler (ive also seen the FIMO sampler, but i much prefer the sculpey sampler cause the colours are waay better). ive got some grey FIMO, but i dont really use it xD

Fimo Soft & Sculpey III

Mainly Sculpey and this random brand I found at the art store called Kreall-therm or something like that... I prefer Sculpey but Kreall-therm has some neat colours and the store gets more of that than they do sculpey for some reason.
I've used some premo-sculpey too but found that a bit too hard.. and I bought white and red Fimo once and it was really rock hard so I don't use Fimo anymore if I can help it..

I use : Fimo Soft/Classic, Sculpey III *mainly now* , Premo, Kato, and Studio Sculpey

I'm not picky, I use anything I can get.

I generally use fimo soft because it is easier to find where i live and sculpy (any brand) when i can find it. I bought a block of puppen in white (as it was the largest pale colour they had in stock) but it is VERY hard and takes a long time to condition. I dunno if you're supposed to but sometimes i mix fimo and sculpy together to make my own colour blends, haven't had any adverse effects yet.

I use Sculpey III, Studio by Sculpey, and Fimo Soft.

Normal Fimo is so hard I hate having to condition it. I think I saw *HanaClayWorks say this before too, but trying to work with normal Fimo bruised my hands. >.<

I use all of them except puppen and studio. I like all the different colours the different brands provide and some colours are only made by certain companies.

fimo classic, fimo soft, premo, and very rarely, sculpey III

(since we couldn't select multiples)

I blend a lot of custom colors, but I like to have as many colors on hand as possible to work with.
