I was in the fishing town of Seward, Alaska last week and saw a girl with the most interesting headband. She let me examine it for a minute and here's what I came up with (I just added better photos because I didn't think my iphone photos did it justice):
It was really easy. The pattern is as follows:
Size 7 straight needles and double points
worsted weight yarn
needle and thread
Cast on 24 st.
Knit garter stitch for three rows
Knit in seed stitch for 10 inches. I slip the first stitch of each row to make an even edge.
At ten inches, *transfer 8 stitches to a double point needle and continue seed stitch pattern for another 11 inches.
To make a tapered edge, knit the first two stitches together, continue the seed stitch, then knit two last stitches together (6 st).
Seed stitch the next row.
K2Tog, seed st, knit last two stitches together (4 st).
Knit the next row
CO and leave a 12" tail.*
Repeat ** for the remaining stitches. It should look something like this:
When you have all three strips finished, braid them, pinning the overlapping parts in place how you like them. With the yarn tails and darning needle, sew the pointed ends to the beginning of the work, creating the headband.
With needle and thread, sew the pinned overlapping parts, making sure the thread doesn't show through the front of the piece.
Sew on buttons.
