You can go to Marcia Hohn site www.quilterscache.com
She has tons of patterns for paper piecing and also a
Practice paper piecing page. It sure makes it easy to do
this type of quilting. Never took a class, just went to her
site and followed the instructions. It also helps if you have one of those "add 1/4" rulers". At the top of her page she also lists different size blocks you can use for these quilts. Good luck in your future work with paper piecing. Betty Lee
