Use a floor polish occasionally that is designed for parquet to bring back the shine lost by the constant usage. Apply a water based acrylic wax to the floor which does not require buffing and let dry.

I remember your kitchen before your backsplash. That is
how pretty your kitchen is. Check out the link from Jan-09
I also think it was me that suggessted the tiny tile
backsplash.

I did not know some would think that is dated. I like
your backsplash. But if you do not, take it down. If you
decide you want to keep it. I think some accessories could
really tie your space together.

My biggest advice is design this for YOU. YES YOU!!!
Not for resale, your sister or your fears about sticking to
neutrals. Instead decorate with your favorite things. What
color are some of your favorite things? Do you like
green from the BS? Then make that your theme. Lets see
more of it in details like dishes, a vase, planter, window
curtains, figurines, object da..........

I do know you are frustrated and I am hoping you will feel
better. Right now I think you have forgotten you have
a truly gorgeous kitchen. A few details will make it all
fall into place.

Here are a few ideas....

A valance can add texture and bring out the color of your
tile

or fun fabric

Art work even if it means you buy a tiny frame to fit
a little nook.

Everyone loves Matisse

Okay I can't help myself. A boxer

Okay this has blue but maybe blue is your color and not green

Accessories.....

dish towles (Only if you like owls)

A triveet but make sure it goes great with the BS

a kitchen rug

Here is the tile I might have suggessted. Again I am sorry.

Here is a room that pulls in green as it's theme. If green
is your color borrow from this image and make your kitchen
your green little piece of heaven.
