Who doesn't love a good 2x2 ribbed hat? I know I do. Plus, they are the perfect gifts. They are stretchy, so they'll fit almost everyone without worrying about size, and they are an easy way to get creative in the details. Here's a simple variation I made for my hubby for Christmas. I'm pretty sure that if you did stripes the top would look like concentric triangles! How neat is that?
2x2 Ribbed triangle hat:
Yarn: Worsted Weight (shown in Lorna's Laces Shepherd Worsted in Franklin's Panopticon colorway, used 1 skein with significant leftovers)
Gauge: not too crucial due to stretchiness, I used recommended needle size and am not a tight or a loose knitter. Adjust accordingly.
Cast on 120 Stitches in your favorite method. I like long tail in Knit and Purl to make a reversible edge for the ribbing, or you could do all knit and pick which side you like best.
Join to knit in the round. Note, if you did a standard long tail or other non-reversible cast on, choose which side of the cast on you like best. If you're doing a folded brim, the side you like should be on the inside, if you're not, put the side you like on the outside.
Work in K2 P2 ribbing for anywhere between 6 and 10 inches (depending on how much of a folded brim you want, as shown I went a full 10 inches). Remember, the bigger the head, the more the ribbing has to stretch. That makes the hat shorter. If you are making it for someone with a bigger head than you, knit for longer than you would for your own head.
Place markers in three evenly spaced K2 ridges (since you have 12o stitches, there will be 30 K2 ridges, your markers should be every 10th ridge). By "in the ridge" I mean in between the two knit stitches that make up the ridge.
Decrease Round: Work in ribbing until two stitches before first marker, K2tog, slip marker, SSK. Continue to work in ribbing around, decreasing in this same way at the next two markers.
Rounds 1&2: Work Decrease Round
Round 3: Work even in established ribbing (Knit the knits and purl the purls)
Rounds 4&5: Work Decrease Round
Round 6: Work even in established ribbing (Knit the knits and purl the purls)
Rounds 7-12: Work in same order as Rounds 1-6
Rounds 13+: Work Decrease Round every round until 6 stitches remain.
Break yarn, pull through remaining stitches.
Weave in ends.
