When the power went out, I quickly learned that I could knit in the dark. It was either knit or go completely mad with nothing to do. Surprisingly, I didn't miss a single stitch in the darkness and, by the light of two small candles, I was able to do some openwork stitches.
Yarn: Medium (4) worsted yarn. I used Vanna's Choice yarn.
Size 9 (5.5 mm) knitting needles.
Cast on 70 leaving a long tail for sewing up seam.

Knit until hat measures 8 inches. If desired, add another two or four row knit stripe of color B to hat.
Bind off and leave a long tail for closing the top of the hat.
To put together, lay out hat on a flat surface. Bring right sides together so that the wrong side is facing you. Pin side edges together, making sure the knit rows are matching. Sew up the side of the hat, starting at the brim.
Use bind off tail and weave it in and out of the last row. Pull tight to gather hat's top and knot in place. Weave in the ends. Turn right side out and wear!
