I have my thread in large (one gallon or more) glass jars. Separated by color family or purpose. They're on top of my lawyers bookcase that I keep my batiks in and they just add more color to my sewing room. You can find these jars at Hobby Lobby (50% off almost every week) they're "antique looking" blue (like old mason jars) with tight fitting lids. Just picked up two more yesterday.
