Stripy Wavy Scarf
This garter stitch scarf is based on the traditional Feather and Fan pattern, but with the eyelets removed. It is knit lengthwise and the stripes are created by changing colors every 2 rows.
The sample was knit in a DK wool, but other weights (e.g., worsted, fingering) would work well. You can change up the number of pattern repeats to change the length of the scarf.
The number of colors, width & order of stripes is all up to you!
