Fine spinning tip

I've been spinning cotton like a mad woman, trying to get good at it. I found that even if I have my tension set to nothing (and by nothing I mean the cord is just hanging over the bobbin, completely relaxed) my wheel pulls to hard for me to control the intake and in turn the fibre slips out of my hands before it gets enough twist into it. What is the solution to this problem? Pipe insulation. 

Putting pipe insulation over the core of the bobbin somehow makes the wheel pull less.  I'm sure there's a good solid scientific reason behind this, but at this point, I'm just happy it works!  Makes spinning cotton ( and other fine yarns) much easier.

You can find pipe insulation at most hardware stores.
