This pattern can be any length, width or use any yarn you desire. This makes it a great stash buster project.

Length: As the title suggests, the project I knit was 12 feet including fringe. You can stop at your desired length.
Width: I you want a wider scarf; you can make it wider simply add pairs of (2) stitches until it is the desired width.
Yarn: I used Aran, but this pattern works for any yarn weight. If you use a thinner yarn, add more pairs of stitches, a thicker yarn will require a pair or two less. The best thing is to knit a gauge swatch with the whatever yarn you plan to use.
