I just wanted to say thank you for your input on my knitterly moral dilemma. I am going to search my stash for suitable black Fetching yarn, I seem to remember some leftover Aurora8 after I finished Mr. Batty's hat. If there isn't enough, or if I really can't find it... I'm getting a ball of black Lamb's Pride Superwash. I think it's my new favorite superwash worsted weight. Lovely stuff.
And... to follow up a question with a question: When you undo a provisional caston, which side do you start on? The side with the knot, which is essentially the beginning of a long-tail caston, or the side with the leftover yarn and the working yarn? I know I've done this successfully in the past, but the last time around, I fouled it up. I don't want to frog again!
