I think it is really cool. I have one ?. Do you intend for the sashing to be different widths? In your plan the verticals are narrower than the horizontals. The little blue corner stones would balance the quillt better if they are also square, imho.
I would make this pattern, It has a contemporary and simple feeling to it. Very nice.
Let us know if you are going to make it!!!
and please post.
peace
