Beautiful work. I think the first one is done with 2.5 x44 "jelly roll"strips and then sewed in one continuous strip and then you cut to the width you want the quilt or wall hanging and start sewing the strips together. Our guild had a sewing day and made these. I can't remember the name of the pattern. I was out of town when they had the sewing day, but got to see the beautiful quilts when done
