    I'm looking for a way to measure a small change in resistance (not
    necessarily a small resistance, just a small change). Is there a
    common configuration of a wheatstone bridge or some other circuit that
    I should consider for this? It is not a problem if the measurement
    ends up being a voltage which needs to be converted to a resistance or
    something similar.

    I'm looking at measuring less then 1 ohm changes in 2-4kohm
    resistances.

    Thanks!

    sounds just like a strain guage, you could use the same ciruit for one,
    should be many examples from google.
