I like the Christine Tesh one...and it's free lol and it's beautiful. I remember when I first started paper piecing, I found her website and dowloaded her primer...it is the best and I learned from that. I also bought her library book pattern then...here is the story...
She said she iwas going to mail the pattern to me and and when I recieve it then I must send her a check. She said that if I didn't pay her etc etc. I can't say it here...but I thought it was the funniest thing I ever read. I am sure a lot of folks didn't pay her on the honor system. I sent that check so quick. hahahahahahah she is a funny lady and very sharing.
