This hat is very easy for beginners because it’s knitted with just two needles as a rectangle and sewn up when completed.
The knit2, purl2 rib is very stretchy so the hat will fit almost anyone. If you’re going to make it for a child reduce the number of stitches in multiples of 4.
I used some double knitting acrylic yarn out of my stash. Any double knit weight of yarn will be fine for this hat as long as your tension gauge is reasonably close.

Row: *(K2tog) repeat from * to last stitch, K1. (9 stitches remain)
Cut yarn leaving about 20″-30″ for sewing up. Thread a tapestry needle with the tail end of the yarn and pass through all the remaining stitches. Draw up tight and sew in. Sew up the side seam of the hat.
