I took a huge ball roving and hand-felted it for awhile in the sink, then I threw it into the washer for a cycle. It came out a nice size, but needed some needle-felting to finish it up. I borrowed a 6 needle felting tool from TWS , tossed a bag of small colored roving chunks at Adam and told him to get to work! He had fun. We are definitely buying one of those tools sometime. We only have single felting needles right now.
