I'm not using any of the linens in the blocks, other than the centers. I did a couple of blocks that way and found I like them better with only the center from the linens. I've also got some rather large spaces which is to allow room for the photos.
This is currently how I envision arranging them:
These blocks won't necessarily remain exactly where they are now. I'm envisioning smaller cq blocks around the center photograph. For now. :-)
