I have been asked several times for the pattern to my snoods. There is one that I used which comes from a video on Youtube. This has a mesh to it. My solid snood pattern is essentially a large circle with a few inches of depth made before crocheting on an elastic hairband. For my blue silk snood, I used one ball of Patons Silk-Bamboo yarn. This is really soft and feels nice against my scalp. You can use acrylic but it will be a bit scratchy against the skin unless you have killed the yarn before hand. I used a size H hook.
