Mine are in a plastic bag.
It serves the basic purpose of not snagging them, but no matter how I tuck them into nice perfect balls they loosen with every rummage. It always looks like a nest of snakes in there and I always take one glance, decide I can't be arsed and pull out jeans instead.
I find drawers even worse for them escaping to either end or worse, getting caught and snagged when I open and close it.
There are people who wear opaques every day! They must have some amazing storage trick I don't know about.....
