Everything where it's supposed to be, neatly. That's about it for us. I really don't like "hidden" clutter, like in drawers or closets, either.
I *will* say, although I know some people will disagree, that I find having a designated "clutter" area is VERY helpful for me. If I'm straightening up, or decluttering, and there's something I want to keep, but I'm not sure where to put it, instead of agonizing over it for 15 minutes, finally deciding, and then ending up decluttering an entire other closet when I have no time or patience for it
, or feeling like I've "failed" at decluttering Space A because I don't know what to do with Objects X and Y, I just toss it in the clutter bin. I have a drawer in the kitchen for little stuff, and a bin in my daughter's playroom for bigger stuff. I go through it periodically, and usually find the right space (often because I've since decluttered the area it would belong), or, when I'm decluttering some other area, I'll remember, "Aha! That would belong here", and I can just grab it and put it where it belongs then
. Much less stress for me that way.
