I, too, have way to much "stuff", glassware, craft supplies, books, clothes, and fabric. I need to declutter and am beginning to with everything except the fabric. I love fabric and find it hard to part with it until I've "made something" with it.
However, I know that when I'm gone my DD will give it away, throw it away, or sell it in a yard sell. I told her it's OK for everything except the glassware that I'v collected. I want her to keep that for a while to see if she developes an appreciation for it.
