There are as many different PP approaches as there are people doing PP BUT....after reading and hearing so many different ways to do it, I decided to learn ONE WAY that felt comfortable for me and stick with it. I used a JoAnn coupon and purchased the "Carol Doak Teaches You to Paper Piece" video and her method works for me so the video was a good investment. However, rather than tear the foundation out, I use the June Tailor "Perfect Piecing" foundation sheets (also from JoAnn when I have coupons etc.). The "Add a Quarter" and "Add an Eighth" rulers (from LQS and worth it!) have also been great for me. The video and the rulers were one-time "investments" and have more than paid for themselves in frustration avoided and time saved....for me, anyway!
