One More Mistake Beanie

The One More Mistake beanie is a textured twist on the classic ribbed beanie. The deep ridges created by the Mistake Rib stitch provide extra stretch and warmth.

I’m not going to pretend I’ve created anything mind blowing here. It’s a simple beanie made with a mistake rib stitch body, which has already been published by dozens of other knitwear designers.

However, when searching for a pattern to use, I couldn’t quite find one with the yarn weight and head measurements that I needed. So, I knit these hats by sight and wrote my own pattern.

Enjoy!

What you’ll need:

Abbreviations:

  • CO: Cast on (we used the classic long-tail cast on)
  • k: knit
  • p: purl
  • p2tog: purl the next two stitches together (1 stitch decreased)
  • k2tog: knit the next two stitches together (1 stitch decreased)
  • ssk: slip 1 stitch knitwise, slip the next stitch purlwise, then knit those two stitches together from the righthand needle.

Gauge:

  • 24 stitches = 10cm in Mistake Rib stitch on 3.5mm needles.
  • Note: we measured our gauge while comfortably stretching the stitches, as they would be stretched while worn.

Sizes:

  • This hat will fit the average adult head (approximately 56cm around, with a few centimeters of stretch).
  • If you’d like to size up or down, you can adjust the number of stitches in increments of 16. This will allow you to follow the decrease section without making any additional adjustments.
  • Keep in mind this hat will stretch a bit when blocked, so don’t worry if it seems a tad small while knitting.

Instructions

Knitting the brim & body

Cast on 128 stitches and join into a round, taking care not to twist the stitches when joining.
Work in 1×1 rib for 5.5cm (approximately 2¼ inches), then continue to the mistake rib rounds.

Mistake rib round 1: *k2, p2, repeat from * to end of round.
Mistake rib round 2: k1, *p2, k2, repeat from * to last stitch, k1
Repeat mistake rib rounds 1 & 2 until body of hat, not including the brim, reaches 14cm (approximately 5½ inches), then continue to the crown.

Knitting the crown

The following rows have progressive decreases that will close the crown of the hat. If you’re using circular knitting needles, you’ll eventually needle to switch to DPNs when the stitches get too tight.

Round 1: *k2, p2, k2, p2tog, repeat from * to end of round.
Round 2: k1, *p2, k2, p1, k2, repeat from * to last 6 stitches, p2, k2, p1, k1.
Round 3: *k2, p2, k1, p2tog, repeat from * to end of round.
Round 4: k1, *p2, k4, repeat from * to the last 5 stitches, p2, k3.
Round 5: *K2, p2tog, k1, p1, repeat from * to end of row.
Round 6: k1, *p1, k4, repeat from * to last 4 stitches, p1, k3.
Round 7: *k1, p2tog, k1, p1, repeat from * to end of round.
Round 8: knit every stitch.
Round 9: *k1, k2tog, p1, repeat from * to end of round.
Round 10: knit every stitch.
Round 11: *k2tog, p1, repeat from * to end of round.
Round 12: knit every stitch.
Round 13: ssk to end of row.
Round 14: k2tog to end of row.

Cut a long tail and weave through remaining stitches, then pull tight to cinch the hat closed.

Finishing

Block your hat and then weave in any loose ends to finish.
