Re: NEC-LIST: Coil-loading.

Crafts stores sell large styrofoam toroids for crafters to use to make door
wreaths. This type of wreath is commonly seen at Christmas (at least in my
neighborhood).

I was in a crafts store a couple years ago with my wife and bought one of
these to play with but never got around to winding it for testing.

Might have simplified the winding process by cutting out a half-inch section.

The "no saturation" feature of air cores always appealed to me.
