Good. But there is a catch. All clay used there has to be bought there at $25/25lbs which is amazingly high. If she really gets into it, she is going to want to throw more even if she doesn't fire more. Getting good involves repetition and developing muscle memory just like a martial art. I guess by that time you are going to have your own wheel (get a shimpo VL whisper BTW) and a kiln (Skutt 1018 is a great size for a beginner BTW) :wink:
Once you have your own studio, you should be paying 10-15 a bag for clay except for porcelain like Southern Ice which is imported from Australia... If you buy bigger quantities and go in with a few people, your prices may fall to as low as $5 a bag for some nice stoneware clays assuming you have a clay supplier nearby.
At any rate, get involved. I was a 2d person for years and my first thing I threw, which was a crime, changed me forever. Welcome to the fraternity.
