I worked my scarf from leftovers in my stash; if you don't have such a big supply of leftovers you can make each stripe a different color or use a pattern of several different colors of stripes of different widths. If you have heavier weight yarn, just use bigger needles and you'll get a wider scarf.
Gauge is not critical, but I got about 6.5 stitches and 8 rows per inch in Mistake Rib.
Finished scarf is 3.5 inches wide and, as shown, 43 inches long. It can be made longer or shorter depending on how much yarn you have.
- Cast on 23 stitches in main color.
- *Knit 2, purl 2. Repeat from * across, ending with a purl 1.
- Repeat this row for 3 inches.
- Change to contrasting color and continue in pattern for 1 inch.
- Change back to main color and work another 3 inches.
- Continue in this manner until scarf is desired length, ending with a section of the main color.
- Bind off in pattern.
- Cut yarn and weave in ends.
To make finishing easier, don't cut the yarn you aren't working with as you go. Instead, each time you get to the right-side edge, twist the two yarns together so the yarn you aren't working with is carried up the side.
Other than that line of yarn running up the side, this pattern is reversible.
If you're working on this project from your stash, you may want to vary the width of the stripes more or use more than two colors. If you're not going back to a color soon you'll want to go ahead and cut the yarn after a stripe is finished and weave in ends later.
