Neck ThingumUsing the longtail method and a 16" circ one size smaller than you would normally use for your chosen yarn, CO the same number of sts you would to knit a basic hat. That's 96 in my case. It's also 96 for my much larger son, because this project is very stretchy. The number must be divisible by 4. Join into a rnd, being careful not to twist (as they say), and place a marker to indicate the start of the rnd.
Rnd 1: *K2, p2, rep from * to end.
Rep Rnd 1 until the tube meas approx 6 1/2", or desired length.
Next Rnd: *K2, pfb, p1, rep from * to end.
Cont now in k2, p3 ribbing for about another inch to an inch and a half.
Purl 1 rnd.
BO loosely, knitwise.
That's it. If you decide to wet block the Thingum before wearing, try not to stretch out the 2x2 portion of the ribbing. The whole idea to keep it stretchy, but snug.
FYI, pfb = purl into the front and back of the next stitch.
Knit one rnd, purl one rnd, knit one rnd, then cut yarn, leaving an end AT LEAST three times the finished diameter, and complete with EZ's sewn bind-off (or casting-on casting off, as she called it) from p38 of the newer edition of her "Knitting Workshop". It looks like purl bumps, but is extremely stretchy, and perfect for the lower edge of the Thingum.
With Xmas only 10 days away, maybe you're looking for the ultimate stocking stuffer (unless you go to Florida for the winter). Since each Thingum takes less than 24 hours of on-again-off-again effort, if you're motivated you could make ten of these before Xmas morning, each one in a different colour. What a great stash reduction plan! What are you waiting for?
