Take the thinnest possible sheet of bog-roll, unwind it approx a turn until satisfaction. Reminds me of Penrose v Kimberly-Clark.

I think we’re getting into negative shim territory here. The sheets often remain misaligned for half the roll (outer halfway over the inner, like shingles) so I don’t see how unwinding once around would fix things.
Thanks anyway : )
