The blocks look about 6". how about making them square-in-a-
square? the added corners would enlarge the blocks and then you could do some sashing, etc. they would set on Point or you could do the action twice to make them even larger and set on square. color suggestions of darker browns & turkey reds sound good. when quilting, use a red or dark brown to stitch about 1/4" inside each star.
will be a great quilt and so fun to finish a UFO.
