Looking for a quick gift idea? For projects that work up in a hurry, bulky yarn is the way to go. One possibility: the downhill skier hat. It'll keep the recipient warm on the ski slopes this year, and will look great anywhere else s/he wants to wear it.
Another possibility: the thick and thin scarf combines bulky yarn with finer yarn for a project that has lots of visual appeal. It's also a really quick project, and you could whip up a bunch of these scarves in time for Christmas gift-giving.
