Pulled up carpet and found beautiful 9 x 9 parquet flood in decent shape. Room apparently a remodel because there is a section of oak strip flooring that extends into another room, as well as an area with just plywood.

Where could I find some 9 x 9 parquet-everything nowdays seems to 12 x 12.

Steps to refinish-what grit of sand paper do I use and what is the best finish process.
