I decided to set the squares with a simple sashing and border. The cream fabric sashing is 1.25 in wide (1.75 in with seam allowances). I used some left-over 2 in green squares which I recut. Then added a 3 in (2.75 in without seam allowance) blue border with orange square in the corners. The quilt top (prior to doing the quilting) measures 42 in X 53.75 in.
So now I have to put the top together with the batting and backing and quilt it.
