The knit hat pattern begins from the band and works its way to the crown. Follow the knitting pattern to cast enough stitches on your circular needle. Knit and purl the round as instructed. Once you reach the crown, change the needles to DPN (double-point needle); that is where you start decreasing the stitches and closing up the hat at the top. Use a tapestry needle to bind off the last round and pull tight to close the gap. Hide all yarn ends and you are done with the knitting part.
