Toni, Here are a couple sites that are interesting, but I think the best way to learn paper piecing is to have someone show you in person. The actual technique is much easier than trying to decipher the written instructions. I put off trying it for a long time because I found the instructions confusing, but now that I've tried it, I love it. Yvonne's post is very informative and Patrice also did a class which included paper piecing.
