Another Christmas project I enjoyed was this simple scarf. You need a TON of stitches on the needle, but they work up pretty quickly and they are pretty! I have already gotten requests for the pattern, which is a free one from Lion brand yarn!
With this blue one (for my Nana, she loves this color), I followed the directions exactly, and used just a little bit more than one ball of yarn. That annoyed me, since it meant I had to buy two! I made a second one, in red, and just reduced the number of stitches (I think by 20 or so) and then it took exactly one ball. I think a little bit shorter looked fine - maybe better, since it was a little less bulky.
Not the best picture I've ever had taken of me...but I was in a hurry to get things photographed and wrapped!
