[Elecraft] Toroid _winding_ insulation (not ends)

[Ward Willats]

I am winding the toroids for my K2 SSB adapter.

After I got 22 turns on this thing, I noticed the insulation on 2-3 
adjacent windings had (rubbed?) off, one on the top, two on the side 
of the core.

Not sure how I did this.

Not sure if the bottom of these wires is making contact with the core.

Does it matter? Am I messing up the lines of force in my inductive 
magnetic field or do I just rewind "to be safe."

(Tried to search the archives, but man, the usual toroid tining topic 
has created so much noise...)

Thanks,
