This is the first in a series of Beanie posts.
Noro Kureyon Beanie. Takes one skein. Knit in the round.
Get your gauge, then cast on the number of stitches based on your head circumference (make the number divisible by 8, more on that later) and how you want the hat to fit. If you want it tight fitting, subtract an inch. If you like it loose fitting, do not subtract.
Garter edge for 1 1/2 inches then stockinette stitch for the desired length (depends on your head size and how you like to wear your beanie: high on your forehead or low near your eyebrows. Measure a hat that you like the fit.)
Note: Garter stitch in the round is: knit a row, purl a row. Repeat these 2 rows for a garter "ridge" or 2 garter stitch rows. Be sure to mark the beginning or end of the round so you know where to change from knit to purl.
When it is time to begin the crown decrease, divide the total number of stitches by 8, (you will have 8 sections) then knit to the last 2 stitches in each section and knit 2 together. (k2 tog) for the entire round.
Knit the next round, no decreases.
Repeat these 2 rounds until you have 8 stitches remaining. Try the hat on to see if it fits. If so, cut the yarn, leaving about a 6" tail.
Thread a tapestry needle and thread the yarn through the open 8 loops. Pull tight to close hole. Weave in all ends, block as appropriate for your yarn, and enjoy! this website explains it really well.
