How to liven up my basement craft room?

I'm organized, that's not the problem. The room is, lets say, 10 by 10. I have one wall with shelves holding all my beads, neatly organized. (I run a beaded jewelry business). Another wall has my desk and a small TV on a bookcase. The third wall has a closet taking up the entire wall, and the fourth side of the room is where the stairs meet. The room is white (and I probably will not be allowed to paint as we're moving next year). I have a cute craft table from Ikea in the center, on an inexpensive brown indoor/outdoor area rug. The room is pretty chilly - I use a spaceheater but I still dread working in that room. I end up taking stuff upstairs and do it in bed or in the livingroom. What can I do to the room to make it more enjoyable to be in? I do have a small decorative mirror on one wall, and a colorful paint chip artwork I did on another. What else can I do to make the room more inviting/warm/enjoyable?
