anyone?????????/

that was probably some sort of a wall covering/paper.
as for other colors, that all depends on what look you're going for. You could go with a solid painted color just like you could use wallpaper.

There are thousands of wallpapers that could be used as well..

the closet would probably be best placed opposite the bed or next to the bathroom. one unique way is to connect the bathroom with the closet for easy accesibility. i hope that answers your question!

I like having a closet off the bathroom so that you have to go through the bathroom to get to the closet, not off the bedroom so you have to go through the bedroom from the bathroom to get to your closet. That way no one can see you from another room in your birthday suit :)
