I've used the clear, the white, and the blue clear washable school glue. All work great. I just open the cap that comes on the bottle of glue only about halfway and then drizzle it on the batting moving very quickly. The glue sort of forms tiny dots on its own this way. After drizzling, I smooth the fabric over the batting with both hands and use a dry iron to set it. I've used the same 6oz bottle of glue for a large baby quilt, two sofa throws, and three table runners. A little goes a long way.
