For me it's keeping whatever I have organized and in places where I know what I have, so I will use it. No matter how much space you have, it's easy to overflow that space and then store things you never use because you forget you have it. I find I need to keep my fabric collection small enough that I know what I have. Organized in a way I can see what I have. Stashing in boxes, etc. doesn't work. Out of sight, out of mind! I am purposely limiting my sewing area because I tend to be a pack rat if I have more space.
