I am for the most part self-taught. I did take two different classes on PP, the first one had me cut out all of the pieces and add on the 1/4 in seam, (what a pain in the pitutte that was, the second was so much better. George Sciliano had this neat little ruler with the swing edge....I fell in love with PP. Now that I have one of Carol Doaks' book, I am anxious to get started on those! I found Quilterscache.com, and have been using many of those patterns. And then I found THIS site, and have been so fortunate to have the generosity of the talent quilters here!
