I like to use 3m 2" wide utility cloth that comes in large rolls. The cloth backing makes it last MUCH longer than paper backed. You can tear it off in whatever length you need. You can also tear it length wise to get thin strips for getting in tight areas. It's pricey, but a roll will last a very long time. Down side is you need to buy a roll in each grit, I have 60, 80, 180, 240, and 320.
