This is my "Jaywalker scarf" (pattern on Ravelry)... Or at least this is what it looked like when I took the picture. I messed up the scarf after that and had to start over - aghhhh!  Anyway, she used six different colored skeins of Koigu sock yarn.  I decided to just use the two different colored skeins I already had here at the house. For one, switching back and forth with two colors is all I can handle. And two - six skeins would cost about $90.00 or more!  With a bout of double vision (still going on) - I'm not knitting as much - and when I do, it is for short bursts of time during the day and evening.  But then again, slow and steady gets the worm!  It doesn't help though that I had to start the scarf over again!!!  Oh, if you decide to knit this, make sure when you slip the two stitches, slip them together (at once)... Otherwise I found (or maybe it is just me) that the holes and little loopy rows don't match up....
