Lori:

In Brewer's Dictionary of Phrase and Fable (1981 edition),
under "thumb" we find:

  RULE OF THUMB

    A rough, guesswork measure; practice or experience, as
    distinguished from theory; in allusion to the use of the
    thumb for rough measurements.

I have been unable to find any other definition, and would be
pleased to receive a sound reference. Cheers,
