We hired professionals

After some, but not much, thought we decided not to sand the floors ourselves....

This is a professional model floor sander that really takes off the layers. Above photos are of the kitchen nook.

And this is the kitchen and looking into the formal entry, dining room, and parlor.  All of the floors on the main floor have been refinished except the laundry, kitchen entry and main floor bath which will be having tile.

Lovely.  When the floors are dry, we will again cover them up with cardboard until the rest of the house is completely done.  Then the guys will come back for one more sanding and final coat.
