What you see in the photos is my on-the-fly creation after seeing the photo of the one in that ad. It involved a little mathematical skill to make sure the initial chain would leave the right multiple of stitches for an even pattern all of the way around. I think it turned out pretty well.
This item will (most likely) be available at the craft show (if I don't fall in love with it too much between now and then). I may have to make an identical one for myself after the craft show... I don't think this yarn is available anymore, so I think I'll keep the rest to make one of these cowls just for me. You know, if I can part with this one at the craft show.
Note to self: for mine, make 1-2 sections taller and 1 section narrower - for my giraffe-like neck. (Or just use a 1-size smaller hook, which I apparently used for the dark grey cowl.)
