Completed January 2, 2015: Scarf using hand-knitting leftovers from a "friend of a friend."  I used Fibonacci numbers to create the stripes (see http://www.mathsisfun.com/numbers/fibonacci-sequence.html and Marg Coe's http://www.e-weaving.com/Fibonacci.html).  I cut out about 8" of weaving twice and eventually rejected an elaborate 12-shaft twill + 4-shaft basket weave salvages draft.  Plain weave with a very thin rayon weft worked best.
