Do you know of a good material to sculpt very small models?

I Don't want to make fixes or small modifications, but make my own miniatures. I've used green stuff for a long time now, but it's a bit expensive, and I was looking for something different to try out. Possibly a bit cheaper but still good quality.
Looking around I found many people using Sculpey products, but the packages for this substance are usually big (at least 500gr), and I have no experience on what happens after baking. Also I don't know which variant is the best suited for my purpose.

Any tips? Also suggestions on different materials are welcome.

I'd stick with green or brown stuff tbh. At 6mm you won't be sanding things to shape much, it'll mostly be clay shaper or needle work.

Greenstuff expensive? You're buying it from the wrong place. Look for Kneadatite (greenstuff's proper name) on the net and you can get a lot for very little.

I should have learn about this a long time ago... this makes everything much easier! Thanks!

Besides the price difference I'd still like to know what's the main difference between the green stuff and the sculpey, and in which situations it would be better to use one or the other. Regardless of sculpting dimensions.

Thanks

Sculpey is oven-hardening clay. Long science short, it "dries" by removing moisture from the clay and thus hardening. However, because you're removing something, the stuff will shrink slightly but noticeably. This reason alone makes it unfit for sculpting fine miniatures.

"Green Stuff" is an Epoxy Putty. You mix the two parts, and the two-part epoxy chemically reacts and hardens over time. Because nothing is really being 'removed', there is no shrinkage.
Additionally, "Green Stuff" is workable until it fully hardens. You can sculpt the general shape, let it harden a bit, then continue sculpting when it is at medium hardness.
Finally, you can add on bits to existing, hardened things you've sculpted. Sculpey requires you to re-oven everything.

There is almost no reason to use Sculpey when Green Stuff and other epoxy putties are so much better for your purposes.
Sculpey may be a nice and cheap way to make large things such as Tanks and such maybe.

Actually I know a fair few people who use sculpey / super sculpey and similar. Predominantly the reason to use it is the extended working time, so it's useful for anatomy etc. On a 6mm though, you don't get a lot of advantage.
