This is a snood crocheted with 100% cotton yarn. I adapted it from the pattern for the hat in: Stitch 'N Bitch Crochet: The Happy Hooker by Debbie Stoller
To make this snood, I just kept doing rounds until I thought that it was long enough, then I single-crocheted over an elastic band. I was really surprised when I put it on...it was quite snug, with very little give. A snood is held in place with pins around the front, and the pins seemed to be much more stable in natural fiber than with acrylic. With acrylic yarn, hairpins tend to slide and not hold very well - I use quite a lot of them - almost 2X as many as the cotton snood required, in fact, to get a good hold. And it held GOOD. Absolutely NO slippage, and it didn't require me to readjust it at any time. A quick spray with hair spray, let it dry, then put on the snood and pin. It's as easy as that, and takes less than 5 minutes. The only downside: weight. It is a bit heavier than acrylic, and I'm tempted to add pins along the crown of my head to better distribute the weight. My scalp is a bit sore where the pins were the day after wearing it. But all in all, I am quite impressed!
