This is one of my new crochet projects for Christmas this year. It has a cotton center and the edge is worked in size 40 crochet thread and a size 12 hook. The "ornaments" on the little trees are crocheted also. If you want to see a better picture of it you can click on the link at the top right of the blog for Crochet World Magazine where it is in the December 2011 issue. Scroll down threw the patterns until you find the picture then click on it for a full size view.
