The color of the crochet cotton is Copper Mist, a copper metallic thread. I just discovered that the brand has been discontinued by Red Heart and replaced by Red Heart Fashion Crochet Thread. This color didn't seem to make the new color card, which is unfortunate, I'd like to make another snood out of this thread.
It turns out that working with the size 3 crochet thread isn't nearly as scary as I remember it being, when I first started crocheting. The pattern calls for a size 0 steel crochet hook (3.25mm). That's a US size D. It's not that tiny for working with crochet thread. It's awesome!
Finished measurements, laying flat are: 2 inches wide x 10 1/2 inches - measured down the center of the band.
Happy crocheting!
