We had and armature and board and were sculpting using Chavant's Le Beau Touche. I've worked with Chavant clay before and it's quite good. Brookgreen had a warming box and when warm, it is easy to manipulate.
I would add, however, for the way that I work, I think that this clay is better suited to larger pieces. Since we were working with a 16" armature, the clay was a bit soft for my style of working. At a larger size, I would think it would be well manipulated by fingers and would work quite well. It did stick to tools quite a bit and I found that I had to keep baby wipes handy to to clean my tools down quite a lot.
The images shown here are at the end of day two and I have probably about 10 hours of work.
