I found this project in an issue of Interweave crochet, so am making it with some cotton from my stash. The yarn has a metallic looking fiber in it and it looks really snazzy.
Thanks to all for the comments about the scam calls. I'm still getting them, however not as frequently. One time I just didn't answer. Another time I pressed the pound (#) key several times and they hung up. Hopefully between the two, they'll finally get the message!
