This is the pattern for the hat that I make the most. I took the best of about 7 patterns that I liked and tested it for every size listed. I have made it in stripes, ridges, plain, etc. I've even tie-dyed one. Fits newborn-large adult. If you make one, let me know! Featured in an earlier post as Badger's Beanie. (Pardon the really basic pattern, but I wrote it originally for a very beginning knitter.) Pattern for Roll-brim Beanie (knit in the round) Notes: Gauge: 4 sts./in. (Row gauge is not such a big deal in this small project.) Suggested needle size 7, or as needed to maintain gauge Sizes: 13", 15", 17", 20", 22.5", 25" (newborn, older infant, toddler, lg.child/sm adult, med. adult, lg. adult. Hats will stretch quite a few inches, and rolled brims allow for some growth. I cast on using the long-tail method, which I recommend as it gives a neat and elastic edge. Materials: Worsted weight yarn - approx. 90-150 yarns depending on size. 100-120 yards will do all but the largest size. Needles: 1 16" circular and one set of 5 dpns (double-pointed needles) except for the 2 smallest sizes which will have to be knitted on dpns only, one 12" circular and dpns, or likes socks on one long circular using the magic loop method, or on 2 circulars. Stitch marker Yarn needleInstructions: Cast on 50 (60, 70, 80, 90, 100) sts., place marker, and join making sure the stitches are not twisted. You will slip the marker at the end of each row. Knit in plain stockinette for 18 (20, 24, 28, 30, 32) rows. First decrease row: K8, k2tog until end of row. Knit 2 (2, 3, 3, 3, 3) rows. Second decrease row: K7, k2tog until end of row. Knit 2 (2, 3, 3, 3, 3) rows. Third decrease row: K6, k2tog until end of row. Knit 2 (2, 3, 3, 3, 3) rows. Fourth decrease row: K5, k2tog until end of row. (Switch to dpns on this row, placing joins between dpns after a k2tog st. Knit with 5 dpns or on 2 circulars to reduce the tension on the joins between the needles. This will help prevent laddering between needles. You will have to slip your stitch marker to after the first st, or place a point protector on the back end of the dpn after the last st. of the row to keep your place. Knit one row. Fifth decrease row: K4, k2tog until end of row. Knit one row. Sixth decrease row: K3, k2tog until end of row. Knit one row. Seventh decrease row: K2, k2tog until end of row. Knit one row. Eighth decrease row: K2tog across row. Cut yarn, leaving an 8" tail and, using a yarn needle, pull tail through the remaining stitches twice. Pull tail through center to the inside of the hat.Finishing: Weave in ends, trim, and roll brim to desired length.
