I am being pestered by the local gardening clubs to conduct hypertufa workshops, something I have been reluctant to do. Can't decide whether it would be good or bad for business. I want to sell my troughs, not teach other people how to make them. On the other hand, I figure some people just don't like getting their hands dirty and will want to buy rather than make themselves once they get a taste of how messy it can really be.

Anybody had any experience with this? If so, how do you set them up. Do you have students bring their own molds?

Thanks for any input
