I ended up not using a pattern (not all mugs are the same size as all the printed patterns are for), and made my own for these camping mugs. I did not want to mess with sewing buttons on, so I simply single crocheted 12, double crocheted into the 3rd chain, counting that as the first chain in each row, and dc across. I measured about 10 inches, before finishing off, then simply sewed ends together (just enough to secure a hole for the handle of the mug).
