What I should sculpt with?

I’m having some serious issues with the idea I showed You in my last note.

As I told You already, I’m not sure what material I should use to prepare base.

I’ve been thinking about using Sculpey, but to make such big base, the cost would be way too high. I also found Milliput putty, which also could be used to sculpt, but it’s expensive as well- making base for those two figures would cost as much as buying one new kit. Typical modeling clay, which I can afford, is way too fragile.

I’m looking for any help in finding less expensive modeling material, which will be durable/stone-hard after drying.

Any ideas?

Take Care.

Diorama?

Record of Lodoss War dioramaSince I’m really unpatient person and I’m going to got both Deedlit and Pirotess kits, I thought it may be fun to put them together in one piece.
I’m not sure, if I can call this diorama, but that was first word which came to my mind.

Here’s quick sketch I’ve done in openCanvas5 to show my idea. Any suggestions are welcome 🙂

I’ve been thinking about materials as well. As for now, my idea is to sculpt base with Super Sculpey, or Sculpey LivingDoll. But first I need to get them. It isn’t going to be easy, nor cheap.

Though, I have no idea, if I’ll ever find place to put them in my room in way they won’t get damaged by any accident 😐

Cheers!
