PVC Skein Winder
This goes through to a how-to on how to make a skein winder. For the uninitiated, a skein is the default unit of thread, and it's that windy log that yarn comes in as well. With this snappy tool, you can wind your own skeins as well. If you combine that with the newspaper into yarn concept, you can make your own yarn and wind your own skeins when you're done.
