It was a bit too unfortunately stripy for me to wear, shame as it fitted like a dream. I bought some FabDye, an acid dye good for dying wool. This is when I learned lesson #2: an unwatched dye pot will boil over and dye your dresser purple. Gah.
Hot water does funny things to wool. It came out a brown/purple marl which I could live with, but the arms are now fit for Mr Tickle. Still I can always roll them up.
34 buttons later (yes, that's THIRTY FOUR) and we're good to go. What do you think?
