Hi Trish,
First the easy answer - the balls. I completely covered styrofoam balls with may 1/4" of Quikwall all at one time. While it was still wet, I took leaves (which I sprayed with PAM so they wouldn't stick to the Quikwall) and pressed them on the ball and left them there. Then I wrapped the entire ball in plastic wrap and layed it on a pile of sand to dry for a day. (Before I put it on the sand I pressed the plain ball into the sand to make a nice smooth indentation for it to dry on). After a day I pulled the leaves off, let it dry about a week, then painted them.
