I also love English Paper Piecing. I'm working on an apple core quilt that is my travel project. I have some purchased pieces, but usually use my junk mail and those annoying cards from magazines to make my own. They too are reusable several times.
I would be glad to share some of my pieces for you to use for a pattern to make your own. Just PM me your address and I will get them in the mail.
Leslie, your quilt is beautiful, and I see the pattern.
