Gauge: 15 sts in stockinette stitch in 4in /10cm

This is a quick and easy knit!

You will need yarn (up to 100 grams for the smallest size, up to 200 grams for the largest size), knitting needles to obtain the gauge, a tapestry needle to weave in the yarn ends and a stitch marker.

Since the hat is knit in the round, you will need either double pointed needles or circular needles for magic loop.
