Catherine Wheel Crochet Cushion

I have started making another crochet cushion and finished one side, the front. I may do a fabric back again or a crochet one. I began by making a Catherine wheel motif in a double knit acrylic yarn to try out a pattern in the book The Complete Guide to Crochet I bought in a charity shop for the nice selection of stitches and patterns. The Catherine wheels in the book were used to make a curtain which I think looked good and as my yarn was double knit instead of a lighter weight yarn I decided to carry on adding more rows to the motif making it up as I went in various stitches until it measured 18" x 18" square and make a cushion instead. I think it turned out okay and I may keep this one. The green is a lot brighter than this photo shows taken with my ipad camera.
