Here's what I've been thinking about for our Guest Bedroom in our new apartment. BL needs a wide open workspace for school and gaming, and I need a craft area with lots of accessible storage.
Ideally there would be enough space in the room for both of these things, and we could each have a "half" to do with what we wish. I'm also thinking that we might want a guest bed in here, so we may need to put my "half" of the room somewhere else. There are several big closets and an office nook, so we'll see what we work out.
