Blocks are set on "point", starting with the upper left corner. I cut my sashings (group one) at 6 1/2 inches; second group I measured off 6 1/2 inches and sewed a strip for the corner stone, then cut the strip to put on the top and bottom of the block....I hope this makes sense to the rest of you...or maybe someone else could explain it better? Maybe If I sent a photo?? What do you think??
