Go for it! About 40 years ago a very dear friend introduced me to clay, but at the time, like you I had small children and just could not justify the time. Fortunately, my children had art classes in their local schools and produced charming clay art masterpieces that I treasure to this day. After I retired I took pottery classes and now enjoy giving them my best pots, some glazed and some bisque fired. We spent the past weekend underglazing. I can't wait to glaze Laura's "Koi Pond Bowl" and Sara's "Caught red-handed ABC dish" (she has a two year old). So DO expose your children to clay and they will reward you and You'll have a Ball, promise!
