Sorry, RedStilettos ... I can't answer your question!
Though I do like that quilt and it is calling to me ... no I do not need another project!
I didn't notice the size of the quilt. But if you knew you could easily figure out the block sizes. Otherwise, it definitely works on a grid format, so you could easily figure out sizing ....... and if you were to do your own thing, you could make the base square size whatever you want, and go from there.
I can see this quilt, could be even nicer by expanding those corners so they joined up to give an on-point effect while creating a border filled with scrappy squares. hhmmmmmm .... am I talking myself into this or what?
