6 sc in 2nd chain from hook. Place marker in last stitch.
2 sc in each sc (12). Move marker.
(1 sc in first stitch, 2 sc in next stitch), repeat around (18 sc). Move marker.
(2 sc in each of first 2 sts, 2 sc in next stitch), repeat around (24 sc). Move marker.
(3 sc in ea of first 3 sts, 2 sc in next stitch), repeat around (30 sc). Move marker.
Continue in this manner for 13 or 14 rounds (increasing the number of scs before the increase by 1 each round) until your radius is about 3", diameter about 6", and circumference about 18". (78 scs or 84 scs). This should make a nice flat disc, which is the hat top.
Work even without increasing. It will start making a bowl shape. Continue even until the depth is about 6". It needs to be long enough and and big enough around to cover a Kindergarten-age child's head and ears.
To create a rolled brim, increase the stitches by 50%: (1 sc, 2 sc in next stitch) repeat around.
Work a few rounds even.
Slip stitch around to give a nice tight, neat edge.
Cut yarn. Work in ends.
If the hat is too "airy", you can weave colored yarns through the stitch spaces. Colored yarns will be very decorative.
This team creates 310 Kindergarten-student sized hats for the Head Start program of the Choctaw Nation of Oklahoma by August. We have done this every year since 2010. This is our fifth year, creating hats for the 14-15 school year.
