Those are so much fun. If you've never done it, or if you've tried it on your own and decided it is too difficult, go to http://www.quiltbug.com/ and read the Seven Deadly Sins of Paper Piecing. It helped me tremendously.
Saturday's class was learning how to make a Christmas tree wall hanging. Here is my progress so far. Pretty cool, don't you think? The green part has 11 different pieces, I repeated some of the darks for a shadowy effect. The tree skirt part has 8 different red prints.
The top part will have a pieced gold star, then I will add borders and quilt it.
