This beanie is inspired by a pattern I saw in The Knit Stitch Pattern Handbook. It's a nice resource of 300 patterns of all types. The repeating wavy pattern caught my eye and I knew that I wanted to make a beanie with it. It's a very simple pattern using only knits and purls which repeats every 5 rows. The result is a fun looking pattern with a nice texture to it as well.
This pattern has a good amount of stretch to it, both vertically and horizontally, so gauge isn't too important. My head is 22", and the hat I made fits snugly but without needing to be stretched. It comes down over my ears easily. If I pull it down tight it fits as a skullcap, but it can also be worn a little bit more loosely.
Materials You Will Need:
- Approximately 55 grams of sport weight yarn. I used Malabrigo Arroyo in the color Sand Bank.
 - US #4 circular needles 22" (or DPNs)
 - US #6 circular needles 22" (or DPNs)
 - Stitch marker
 - Tapestry needle
 
Skills You Will Need:
- Casting on
 - Knit
 - Purl
 - K2tog
 - P2tog
 - SSK
 - SSP
 - Weaving in ends
 
Begin by casting on 126 stitches, or whatever multiple of 14 you think will work best for your hat, onto the smaller needles. I used the long tail cast on. Place your stitch marker here to designate the end of your row, and join in the round.
Knit 2x2 ribbing for approximately 1 inch. Now switch over to your larger needles for the body of the hat. The pattern repeats every 5 rows. Knit this pattern as many times as you need until you have a total of 6 inches of knitting, including the 2x2 rib brim.
