The Mistake Rib Beanie – Barely a Pattern

Yarn: Louisa Harding Kashmir Aran, 2 skeins (I used color 12, a lovely silvery grey)

Needles: US 7 16” circulars

Gauge: 22 st over 4” in stockinette. Gauge is not particularly important for this pattern – more important is getting a fabric that you like. I usually aim for a fabric that is fairly dense and tight, but that has some give. Mistake Rib is extraordinarily forgiving and very stretchy, but you still want it to fit tightly.

Mistake Rib in the Round

R1: k2, p2 around

R2: k1 *p2, k2* until last st, k1

Cast on 120 stitches. Any cast-on will do, although I like to use the long-tail cast-on because of its stretchiness.

Start Mistake Rib. Continue until the hat measures the same as the length from the bottom of your ear to the start of the curve of your head. If you want to be able to cuff your hat, add three inches to this measurement.


When you are ready to start decreasing, place stitch markers every twelfth stitch. The stitch to the left of the marker should be a knit column – focus on this stitch when making your decreases – these stitches will remain untouched. These are not typical decreases – in order to keep the mistake rib pattern basically going, the decreases do not occur in the same place on every round (i.e., not necessarily before the stitch marker every time). However, the stitch marker denotes a twelve-stitch (and decreasing) “repeat” in which the decreases will happen in the same way. In most cases, the decrease will occur on two purl stitches, rather than knit stitches. Keep in mind the mistake rib pattern and things will make sense in the long run.

Round 1: *k1, p2, k2, p2, k2, p1, p2tog* (11 st)

Round 2: *k2, p2, k2, p2, k2, p1*

Round 3: *k1, p2, k2, p2tog, k2, p1, k1* (10 st)

Round 4: *k2, p2, k2, p1, k2, p1*

Round 5: *k1, p2tog, k2, p1, k2, p1, k1* (9 st)

Round 6: *k2, p1, k2, p1, k2, p1*

Round 7: *k1, p1, k2, p1, ssk, p1, k1* (8 st)

Round 8: *ssk, p1, k1, p1, k2, p1* (7 st)

Round 9: *k1, p1, k1, p1, ssk, p1* (6 st)

Round 10-12: *k1, p1, k1, p1, k1, p1*

Round 13: *k1, p1, k1, p1, ssk* (5 st)

Round 14: *ssk, k1, p1, k1* (4 st)

Round 15: *k1, ssk, k1* (3 st)

At this point, you should know have 30 stitches on your needles. As you work the next round, remove all the stitch markers except for the one marking the beginning and end of the round.

Round 16: *k3, ssk*

Round 17: *k2, ssk*

Round 18: *k1, ssk*

Twelve stitches remain. Cut yarn and draw end through the remaining stitches. Weave in ends. Block, if desired.
