Babe Cave Inspiration

We have two extra bedrooms in our house right now: a guest room and what is someday going to become half man cave half craft room/office, or what I like to call babe cave. In our future house, we plan to have a whole basement for this kind of stuff, but for now, we're making do with the one bedroom. It's currently taken up with mostly wedding stuff, but I do want to get some organization in place for all of my craft stuff and make it a little more aesthetically pleasing. Maybe over spring break?

I have a desk from my bedroom at my parents' that I plan on bringing over, but I'd love to add some additional storage. I also want to do a gallery wall above the desk to hang all of my girly decor that doesn't necessarily go with the rest of the house.

Here's some Pinterest inspiration I've collected so far:

If you have a room like this in your house, how do you decorate and organize it? Any suggestions would be appreciated!
