I did not take this class. In fact, I don't think the class has been held yet. Now, this is a pretty standard price for a class. It usually varies from $100-250, depending on materials needed and difficulty.
This was my first try at this cuff, and I think it was pretty successful. There were a couple things I would do differently if I were to do it again, but that comes when you are self-taught. Thus the reason I used copper and aluminum wires before trying this with sterling silver or gold filled wire.
