That is a beautiful pattern. I love the fabrics also. But, I too have fabric at home that would work. I don't know anywhere you can purchase the pattern. But, maybe if you wait a bit for the kits and fabric to sell out, they may offer the pattern then.
I could probably figure out the center of the quilt myself. But, I would definitely have a problem with the on point settings and figuring out the dimensions.
Thanks for sharing though. I really like the pattern.
