I had a lot of 12" squares left over from a pieced backing I did and many strips 2 1/2" and 2" so I decided to cut the squares into strips and make a scrappy. I have many blocks to sew together so the placement of these squares is not final. I want your opinion whether I should have sashing between the squares? I am excited about this quilt but a little hesitant how to do it or if it is even worth the time. Help!!!!!!

Thanks for your time and Happy Quilting
