I did this in EQ7 using 4" blocks. The parts are very simple and a lot of it could be done with jelly roll strips. Just the two types of triangle blocks have sharp angles.
I think it would go together with blocks like this and pieced sashing strips.
I saw a quilt in a magazine that had these types of colors and it looked old fashioned and cozy and I was fortunate to find these jelly rolls and ordered them.
