Most of the stuff is on top of carpet, and all you see when the stack is removed is a clean carpet, maybe with a temporary ridge left where a box was placed.
However..... there are eighth-of-an-inch thick layers of dust on * top * of some stuff, which I just vacuum off, or wipe off.
About the clothes: I see the same types of clothes for sale at flea markets for $1 each. Women's shirts, blouses, skirts, tops of all sorts, on display on long, long rows of hangers. Maybe they sell very slowly, or not at all, who knows? Not me.
Maybe it's a regional thing. I've read websites saying that clothes sell well at garage sales. Not around here! Maybe they need to be high end. Oh well.
When I get sick enough of them, off they'll go to donation.
Yesterday I got luck in my decluttering of the bedroom. I found a lot of actual junk that I could toss into the garbage can, and not worry about the value of. Empty deodorant sticks, half-used cosmetics, empty plastic bags, etc. Yay!
