Thanks a lot for your lovely comment. Yes, it's stone. There are different kinds of soapstone, ranging in hardness from very crumbly to very very hard. This one isn't that hard, I could make striations with my fingernail if I'm not careful. I used files to carve the rough forms, sandpaper after that to make things smoother. In the end, I polished it with polish (it was a special kind of stone polish, but I don't remember the name, or brand).
I guess you could buy soapstone in an art shop that sells more than the usual paper and pencils. I'm not sure, but from what I've heard from Leah I think it's rather pricy. But you should try it, you could make some amazing things.
A she-bear, huh? For me it feels more like a he-bear. What kind of animal person did you think I was? Apparently, people tend to think I'm a dog person, but I don't like dogs that much. But I like bears (and cats!) since I was an infant. So, what kind of animal person are you?
