my quilt group went to the beach over Columbus day weekend and we always have a project, and this year it was the disappearing 9 patch. We made blocks, 2 each in opposing design, and then quarter cut them. thru all one design in a big basket and passed it around, then did it again with the other blocks, then we sewed them together just like yours. Real scrappy, I am putting Minkee on mine and it will be my snuggle quilt this winter. They say it is going to be cold and snowy in the Northwest this winter. so I will be ready!!! Jan
