I don’t know if I can set a sweater down without folding it loosely, lol. It drives me nuts that my son will pull out a T-shirt, consider wearing it, then go for another or take off his pants at the end of the day. He doesn’t fold the clean shirt or still-wearable pants. They get all wrinkled and have to go through the laundry (or at least the dryer) for the stupid reason that he didn’t shake them out/ smooth them.
I can’t imagine not folding socks—how would they stay in pairs?
The only things I prefer not to fold are bras & panties. I’d much rather have a drawer can toss my drawers into loosely. At the moment, I don’t have that much space, so my undies are stacked neatly. Most of my bras have usually been worn and are hanging out in my clirty (neither clean nor dirty) space.
We have a flipfold, but I rarely use it. Son will use it if/when I force him to (but it’s a smaller size, so if he’s going to use one regularly, he needs a new one). When he was 10, he thought it was nifty and loved being able to fold things. At 17, the thrill is gone. It was great for folding a bunch of shirts precisely for storage, but I can’t see using it in my daily life.
Besides folding, I also have sorting mania. Not enough that I ever got my son’s LEGO sorted like TG, but I have enough tights for two compartments of the hanging thingy where I keep them, so they are separated into with or without feet. My sweaters are spread over 3 shelves: cardigans, T-necks, and other sweaters. And so on.
