What shape is your room? If it's square a round table would be great but if it's rectangular then a farmhouse type table will work. Either shape will work with your beast, just watch your wood tones.

Wow, tons of potential! The windows are fabulous. I would put the beast in the center of the windows, remove the wallpaper for sure! Then a farmhouse table would work perfectly. Are you keeping the desk, moving it to another room? If not, you can make your own farmhouse table by buying wide wood planks and screwing them onto the top of the desk. We did this with an old small table, total cost was $60.

What wood tone for the.....table? I'm confused. I wouldn't have it match the beast, too matchy matchy. Instead, paint it white or have it match the gorgeous window trim. If you paint your walls a soft white and match the table to the trim it would be stunning.

And yes, losing your mind is all part of the fun but don't worry, it'll come back!

Yes Maureen! I think you just summed up what I was having difficulty putting into words. I was almost wonder if a glass top table such as West Elm's Jensen table might work? Those wallpaper samples are pretty.

I really like that table, but I wouldn't go with the matching chairs. Maybe a chair like below (see pictures above for the look). Then add a fun chandelier (and wallpaper if you go that route).

White is nice as well, and the pictures may help to imagine.
