I didnt realize. I have about 100 pounds of water based clay for my sculptures and pottery, so I have lots of experience with it and keeping it wet and workable for long periods. I made a 7 foot sculpture that took a few months, and it held together though the drying/firing process.(what a pain in the but getting it into the kiln!) If the clay dries uneven it splits and cracks and wont stick to other clay, so sometimes it can be a pain to keep the moisture content uniform. Also, when you sculpt with it, the forms you make must be hollow, or they will break when you dry them/fire them. (obviously with this project I will not be firing the sculpt, so a solid piece will be ok.) I may try it, but I am really interested in trying out some oil based clay, if not just to expand my knowledge and try something new. Thanks for the info.

Water clay works fine for the things that you list. If you cover the sculpt with a wet towel and a plastic bag, it will remain workable for over a year. You can also vacu-form right over the wet clay. ...And it's cheap and available everywhere.
