Now I know this is my first post but.. I'm a senior in highschool and have been given an opportunity to sculpt one of my drawings. I have 9 weeks (the last quarter) to do this project and frankly.. I'm a little nervous. The thing I'm going to attempt to scult is a chair.. or throne if you will.. made out of skin and body parts. It's going to be approximatly 20 inches wide and about 30 inches tall at it's highest point. Big for a first sculpt I know.. my instructor is going to provide me with the clay but I am not so sure it's the right kind.. I think it's a pottery-type that will crack easily. I'm just wondering if anyone had any advice for a very new beginner to sculpting.. such as a specific clay to use.. or maybe a certain tool I need.
