I bought a homemade drop spindle today that was made using cd's and a dowel rod. I paid the lady $5 that had made it. I knew I could make it much cheaper than that, but I figured that was cheap enough, not to have to do it. :D
Even though the stuff I'm creating doesn't look like yarn yet, I know it works good because I watched the lady demonstrate on the one she sold me, and
hers looked great.
Here are instructions for making one.
