Wow!

Overdying the skein that had naked patches worked, and I'm really pleased with the result.

Before:

After:

Admittedly I reskeined it in an effort to be a bit fancypants, and it's in two mini skeins now because I did something silly when I opened the knots holding the skein together. Anyway, I'm really pleased as the ugly naked patches are no more. I could get into this... Now I have to work out what to make with it.
