Last week a few of regular Essen knitting group "members" met at one knitter's home for some knitting (obviously), chatting and ball winding! One of us has a swift and a ball winder and she was kind enough to bring them with her. I brought half my skeins with me and wound them all to pretty center-pull balls!
Here's a little film I took from the process. Just German audio, but you'll get the point just by looking (and notice the interested cat!)
