I have no problem with teflon.After the first turn,it'll hold itself in place.The trouble with any adhesive tape is that it is far too thick.When winding with thin wire,like #38.for example the tape can take up as much space as the wire.Not practicle.I do prefer 3/4 or 1 inch wide teflon,1/2 is harder to work with.

I,ve had no problem keeping teflon in place.After the first turn it stays put.I prefer 3/4 or 1 inch width,1/2 is harder to work with.The trouble with any adhesive tape is that when winding thin wire for example #38,the tape can take up as much room as the wire.Incidentally,with modern wire,inter-layer insulation is usually not necessary.However,when using wire of unknown quality,it is better not to take a chance.

Tough Kapton tape is very good.
As i recall Teflon does 'cold flow', it creeps out of the way wherever it is under pressure. Your artistry with nice uniform tape winding may prevent any problem with the creep.
