For those who remember Dr. Seuss, a Thneed is a Thing you Need... :) Thneeds can be a scarf, a shawl, a hood, a muff, a giant pocket/purse, and any other number of a combination of things you need at the moment... I've even put one on like a tube dress. It's effectively very similar to the Magic Scarf, only a bit more flexible in its uses. Instead of being a skinny tube like the Magic scarf, it's a much wider tube, allowing for a number of different ways it can be worn.
Needles: US Size 17 circular
Yarn: Lion Brand Fancy Fur or other combination of eyelash yarn with another yarn, such as Sensations Sprinkles and Moda Dea Jai Alai. Typically uses 4 balls, although more or less can be used as desired.
Gauge: BIG. Trust me when I say that gauge on this project is not an issue.
Time: Depends upon how fast you knit, but one can easily be done in a weekend.
Using a stretchy cast-on, cast on 80 stitches. Join, and knit in the round until you almost run out of yarn. Bind off using a stretchy bind-off. See, wasn't that easy?
