I haven't had much success lately. I did sell my daughter's pack & play for $40. I listed a bunch more baby stuff on a local facebook buy/sell page, but no bites yet, just one lowball attempt. Then tonight I was looking on eBay and found out that the same things are selling there for more than I've been asking, so I'm in the process of listing it there instead.
theadvicist, I am exactly where you were wrt husband's clothes. He has SO MUCH, and I refuse to put away his laundry because it's such a mess. But he rarely puts it away, either, so there's always at least 1, usually 2 or more, piles of clean folded clothes sitting around the bedroom. I might konmari his drawers and see if it makes a difference. In the past I've straightened up and folded his stuff, but he would just dig through the stacks and make a mess, which bothered me, because it seemed like an insult to my work. So I think I'll take your approach and just do it once and see if it sticks.
My kitchen stuff needs to be the next category to konmari. I have a teeny-tiny kitchen and a zillion things that I never use. We have a crock-pot that got used once and then stopped working. A cupcake display thing that was used once, at our wedding 4 years ago, and has been sitting in the box ever since. An ice cream maker that was a wedding present, and I don't want it because I'm no longer friends with the person who gave it, so, y'know, negative associations. Et cetera. I'd love to toss our mismatched dishes and silverware and get a nice basic matching set, but that costs money, so I've been putting it off. I've done little bits with the kitchen, but I really need to set aside an afternoon and just do the whole thing in one go.
