I am a pp junkie and I truly recommend Carol Doak. Her directions are so clear. AND if I can learn it anyone can. Seriously, I have blocks up about learning new things and I learned pp. If you have questions, I would be more than happy to help you.
Not perfect at it, but have come a long way :) Made a misktake last night that most people would have left but I tore it out and fixed it. (hush Bonni :))
