Many moons ago in the lab I worked we had a guy who made all the special

I learned from him to use what he used :-)
In between windings he used a thin layer of Kaptan foil (polyimide, thin
light brown, slightly transparent) held in place with a simple piece of
normal electrical tape.
Then the next winding, insulation layer, next winding, etc.
This kaptan is heat resistant, thin and also provide s good isolation.
Sometimes you find it as a foil used in old electrical devices,and you
only need a little.
