Jeanie, I checked the Rosie thread earlier today. It is 10" PP blocks, but only 20 of them. I didn't look at them too closely, but discussion said you had to copy the PP patterns from the book. The PP skills I have learned doing the PC blocks I will use when faced with a block that's difficult to piece using rotary cut methods. Doubtful I will make another quilt strictly PPing. The riders on the trail have kept me going in this endeavor. Thanks so much.
