Twenty-seven to go! Tonight I finished ironing the seams open and then I sewed the centermost vertical seam to make one big quilt top. Post haste - I sewed the first horizontal seam. Then the second one. Then I hung it up and admired it for awhile. It's amazing what a few less raw edges will do for ya.
The current quilt is now in two pieces with all the columns of squares sewn together. It was tempting to sew the two halves together but I know from past experience that it's easier to iron the seams down if you do it in chunks. Iron both sets, sew the middle seam, press that and move on.
