I love making mosaic garden spheres, but sometimes the base can be expensive and ridiculously heavy. I've done a few bowling balls, but the adhesive isn't always a correct match and can crack off and it's still going to be crazy heavy. Enter the old, relatively useless basketball found down by the river. I cover it with two layers of fiberglass mesh and thinset and then it's good to go! Here is my psycho creation before grouting. Pictures to come soon of the finished product. All of the half sphere bump-outs are handmade by myself and who doesn't love glittery orange glass?
