I was just looking at this yesterday...She uses a four patch and combines the 4 patch...let me see if I can find the link. I decided to try to do it with some 2.5" squares I'll create out of strips, etc.

Check out the scrappy Double Irish chain. I'm fascinated by the idea.
I like her ideas. I just don't know if I can make mine come out like that or not. I'll have to study it more.
Thank you for sharing this with me.
