I understand your frustration. It seems we spend the first half of our lives acquiring stuff, and the second half getting rid of it. Most of us are frugal by nature (quilters are probably more than most) and it seems a waste not to use what we have paid for. But there comes a time I think we just have to let go of some of our treasures, and rejoice in the fact that they are going to good homes/causes..
I am an only child and after my mother died I had the sole responsibility of cleaning out her house and disposing of countless bags of junk--and some pretty shocking private stuff that I am sure she would rather I not have ever seen if she had known what was coming. That experience did impress upon me the need to clean out excess stuff and private things so my daughters would not have so much to deal with after I am gone!
