the sashing always put me off quilt as you go, I'm not a sashing fan at any time. I'm doing my 365 challenge quilt as you go with the thinnest batt possible (hobbs thermore, split in two). Each block is bound just like a quilt then I'm stitching the blocks into the whole. I'm loving them, but it would be hate with thicker batt. I may have put a tuit up on a 365 thread, don't remember now
