Astronomy question

Suppose that I were averagely familiar with the stars of the night sky (of both hemispheres, to forestall argument); in other words, I'm able to spot the big famous constellations.

How far from Earth would I have to travel so that with careful naked-eye attention I would be able to tell:

1) that the stars aren't quite in their usual positions?

2) that the constellations are no longer recognisable?

Answer in miles, km, ly, pc, whichever units you please; I can convert. If you can show your reasoning, that would be even better.
