I cut my sandwich a couple inches larger than each block. Quilted each block. Added sashing front and back. Trimmed to 1" from seams as sashing cut at 2-1/2". Top stitched second edge of back sashing from back side (not happy with how it looks on front since apparently I can't make front and back match up as accurately as I wish). Getting ready to sew strips of blocks together. Then add border. Nearly done!
