I know it's a bit odd to model a woolly scarf in a t-shirt on a nice day!
The hood tends to fall down easily too..not sure how to fix that.
I have a bit leftover from the fourth skein of yarn, so the yardage estimation seems right. As another person mentioned I would recommend knitting a few more rows on the short end of the scarf, just before the buttonholes. I think this would make it drape and fit better. Altogether I would say I am 4 out of 5 stars pleased with the FO.
