Without digging them out of the closet.... four down with four next to it down covers a queen bed with sashing in between them. So eight on a bed = queen top. I have some of the material that goes with it to use as sashing/borders but not enough for the backing. I've bought what I think is the closest to use but it's not what I want. One of these days I will wake up with the solution and have the top done in a day or so. :-) I just don't want to screw it up.
