Hello
I am trying to make hypertufa spheres, using several small balls. I have covered the balls with fiberglass dry wall tape. However, I am having difficulty getting the hypertufa to stay put, as gravity is not helping at all. The hypertufa keeps dropping off the curve of the ball as I apply. I thought using the tape would give the hypertufa something to cling to. I have managed to cover one small ball but it was a fluke, as I have not been successful with any more.
Any suggestions? Thanks in advance.
