Rolled-Brim HatThis hat is knit in stocking-stitch.
Note: This pattern should be worked in the round, but if worked on 2 needles just add 1 stitch to every stitch count, and leave a long enough tail to sew the flattest seam that you can.
Supplies: Yarn and needles to knit to the gauge of about 4 stitches to the inch. This should be about a standard worsted-weight yarn on size 7 or 8 needles. You should be able to knit any size hat with about 4 ounces of yarn.
The head: Measure the intended wearer's head. Subtract 1 inch and multiply the result by 4. For example, if the head is 21 inches, subtract 1 for 20 inches, multiply by 4, for a result of 80 stitches. Cast-on that number of stitches in a very simple stretchy cast-on. I recommend the thumb method. The cast-on will get no wear and will not be visible. Knit in stocking-stitch until work measures 8 to 10 inches from the start. This can be approximate as the bottom rolls up.
The crown: Decrease 6 stitches every other row. I recommend the k2tog decrease as the simplest and fastest. Whether you stagger these decreases or not doesn't matter. If you line them up it will give the crown a pinwheel design. When between 12 and 16 stitches remain make 2 decrease rows without a plain row in between, leaving between 6 and 10 stitches. Cut the yarn leaving a tail, and run that through the remaining stitches. Fasten off securely and weave in the end.
Variation: From the crown down!
The crown: Cast on 8 stitches in a very simple cast-on, leaving a tail. Increase 6 stitches on each of the first 2 rows [I recommend using the m1 increase which is done by knitting into the stitch on the row below, then knitting the stitch]. You should now have 20 stitches. Increase 6 stitches every other row until you are within 6 stitches of the number of stitches it takes for going around your head, as figured above. Alter the number of stitches on your last increase row so that you end up with the correct number.
The head: Knit straight in stocking-stitch until it is the desired length, usually between 8 and 10 inches. Cast-off as simply as possible, using a stretchy cast-off. Work in the tail. Take the tail at the crown of the hat through each of the cast-on stitches, pull firmly, fasten securely, and weave in.
Let the brim roll up. Tah-dah.
