Slouch hat, no pattern. I think it was size 10 29" circular needles? Maybe they were shorter. I don't remember how many stitches I cast on at the start, either, but I measured my head and multiplied by 4. Lion brand acrylic, after the ribbing it was 8 rows stockinette (brown yarn) and 8 rows garter stitch (teal). Increased every 20 stitches until desired slouchiness and then started a fast decrease every 8 stitches, finished on size 8 dpns (didn't have size 10 dpns).
