I found out about this today and I'm so in. :D I have always wanted to do this so it gives me an excuse to actually haul everything out. I have just been given an abundance of beautiful natural wool that's just screaming for color and I can't wait to do this with the kids. It will be a huge mess but think of fun!
I'm thinking of dying some red yarn for James bag so that's even more added incentive. :D Then all I have to do is get my hands on some black to complete his trio of cool pirate colors: red, white and black.
