I got all the 6 1/2" strips sewn and cut into 6 1/2" pieces. Since I have two, and three, sets of each pairing I laid one set out on the bed and then matched them up with another set. There are no duplicates in all this. I couldn't fit the final row of three on the end of the bed.
I have 25 sets of sewn strips to cut into 3 1/2" sections... after I iron them.
