This is how my built in book shelves USED to look: Very wood. Very shiny wood.
Just a few days and some paint. It really wasn't as bad as I thought it would be. I've been putting it off forever. But it's really so so so much better.
I opted to leave out some shelves in order to place some bigger scale pieces ( that's a professional term for stuff). I don't know if I'll leave it like this or not.
