Experiment: We removed most of the rugs from our home about a year ago. what we found under them was an interestingly beat up mismatched and beatup varnished solid wood floor that hadn't seen the light of day (or night) in over 30 years that we knew of. well we finally got around to the experiment. a little sweat equity and some polyurethane put some life back into them. now turning into a semi whole house project of the next year
