I received Carol Doak's paper piecing DVD from my mentor here on the board and bought the 1/4" ruler. It makes paper piecing so much easier. She also uses a postcard that she tapes to her 1/4" ruler. It makes paper piecing go so fast. You might find her on YouTube demonstrating her method. It's awesome!!! I tried paper piecing without the ruler and was discouraged. After watching the DVD, I can paper piece pretty easily. Thanks mentor for the DVD!! You are awesome!!!!!!
