Joining ends of hat

How can I join the ends of a rolled watch cap? I knitted using straight needles, not circular, and now I need to sew the ends together to make it a hat. Do I just literally sew them together using a yarn needle and then turn the hat right side out? Thanks!

Pull your yarn through the remaining stitches with a tapestry needle and pull tight to close the very top, then use Mattress Stitch to seam the side. It will look loverly! :wink:
