We have a very small home and clutter tends to get the best of us. :( - So here's my motto.
If you haven't worn it in year, get rid of it.
If you haven't used it in 2 years, get rid of it.
If it has some special meaning, be creative with it.
If you can't seem to let go but it sits without being used, see if others could get some value out of it.
