If you are looking to sew paper pieced ones, there is a source you can use for tree ornaments. The Quilters Newsletter Magazine site has a current project called Christmas Flag. It is for making an American Flag with rows of tiny PP squares. The patterns are really cute and I am going to do a few as ornaments. You go to the magazine main site and click Web Extras. Look on the drop down menu for Christmas Flag and click on it. There are free PP patterns for the blocks until Nov. 6.
