My free Bernat Disco yarn arrived last Saturday! The color is Aqua Velvet. Bernat has also been shipping free skeins in Mr. Brown, which looks like a light chocolate to me (but some people have referred to it as Mr. Poo on message boards/blogs/listserv messages!).
I also filled out an offer form for a free skein to be sent to Mom's house. It hasn't yet arrived, but a mixture of the Aqua Velvet with Mr. Brown might be nice!
Now...what to make? I'm very into machine washable items (since hand washing is not my thing), but a scarf or trim on something is a possibility. Or I can add these to my growing use-for-freeform crochet yarn collection.
