Thanks Shirley. Now if I used a basketball size, about how long would it take to cure? Also I'm thinking of adding some small stones for decoration, do I add them after them they start to cure but are still soft?
Boy that was fast! Thanks, it won't be for a couple more weeks before I attempt this as we are still exhibiting at shows until next weekend - but then I'll be ready to take a break for awhile and thought this might be a fun project - one for myself and two for my best gardening buddies. When I get started, I'll be sure to take pics.
