Another idea for using an empty thread cone is to place a bottle of glue in it upside down when your glue is getting low. Of course you would have to have a cone with a large enough opening to the size of your glue bottle. But there are yarn cones, and other cones out there that might be just the right size. Before tossing out those cones, think of what you might be able to use it for first.
