I found a free pattern for an easy headband/necklace, link here. I doubled the foundation chains to make it a little wider and I will tea stain it when it's finished. I'm using a size U.S. 00/2.7 mm steel crochet hook with my Aunt Lydia's Crochet Thread Classic 10. I like the fabric that the hook and thread are making, so I'm calling this a winner.
Here's what I've done today (about 18 inches).
This is a closer shot of the scarf.
