I finally finished my scarf last night. I wanted it long so I could pretend to be Isadora Duncan in my car (not really).
If you want the pattern - which is EASY - here it is.
I used two yarns - 4 ply grey and 2 ply dusky pink and knitted on 6.5mm needles. You'll have to swatch it up to get the effect you want - but you can use pretty much any gauge or any yarn and just adjust the number of stitches.
Cast on 35 stitches (or any multiple of 3, plus 2 extra for a wider or narrower scarf)
k1, *k1, yo, k2tog repeat from *, k1
Continue until your scarf is long enough!
