53½cm I approximate 96 stitches = quadrants of 24
Kfab is knit front and back to make a stitch.
Round1: Cast on 4 and join the round.
Round2: Kfab all 4 stitches (8st)
Round3: Knit all stitches (8st)
Round4: Kfab all stitches (16st)
Round5: Knit all stitches (16st)
Treating as 4 quadrants (4 quadrants of 4 stitches each)
kfab first and last stitches of each quadrant on increase rounds, and knit a rest round after each increase round, thus:
Round6: kfab, knit 2, kfab / kfab, knit 2, kfab /
kfab, knit 2, kfab / kfab, knit 2 kfab
(6 stitches per quadrant, 24 stitches)
Round 7: knit all stitches (24 stitches)
Round 8: kfab, knit 4, kfab × 4 (to increase to 8 stitches per quadrant, 32 stitches)
Round 9: knit all stitches (32 stitches)
Each increase round number corresponds to the number of stitches per quadrant.
Knit to round 24 (96st total). (for a brim of ~54cm)
note: I measured at this point and was elated to find it measured 53½cm
Knit length (to nape /brow)
Change to single rib and knit to preferred length
I decided to bind off with a needle a size up for a stretchier finish (5mm).
I crocheted a school logo on the front in chain stitch.
