I love the 1898 Hat by Kristine Byrnes. A commenter asked me how I knit the two-color headband section.

Necessity is the Mother of Invention as I had a limited amount of yarn for a hat so I adapted the pattern to my needs. I made a slight modification to the pattern by using two colors for the band.

***For a two color band:
Using provisional cast on, CO 12 stitches in Color A, 3 stitches in Color B, and 12 stitches in either Color A or B, leaving a 20 inch tail. (If you prefer to seam instead of graft the ends together, use your preferred cast on, but leave the same length tail.)
Set up row (WS): Color B Sl1, k11, pm, sl3 wyif, pm, Color A  k12*  Make sure to twist the two colors to avoid a hole. 
Start back of headband:
Row A (RS) = Color A Sl1, k to marker, sl m, Color B k3, sl m, Color A or B k to end.
Row B (all WS rows) = Color B Sl1, k to marker, sl m, sl3 wyif, sl m, Color B, sl m, Color A or B k to end.

Any questions regarding the original pattern should be directed to the designer, Kristine Byrnes. This modification is for a two-color headband.
