Do you have one?

Ms. Mary's post on her amazing closet got me thinking about 'the woman cave.' In fact I have just plunked down the deposit for furnishings for MY room - a music room/library, and I'm fulfilling a fantasy I've had since I was a little girl. I'm getting a goosedown filled chaise for in front of the fireplace! Right now it is empty except for my piano.

Do you have a studio, sewing room, green house, home gym, office that you can call your own?
