Personally — and I should prefix this by saying I'm not obsessive-compulsive, honest — I seem to have devised a system where I wash seven "units" of laundry at a go. One unit is t-shirt+pants+socks or a sweatshirt. Jeans, duvet cover, or fitted sheet+two pillowcases are each two units.
This means I know if something's gone missing between loading and unloading the washing machine, and invariably I find it in a duvet case. Or not: having got frustrated at how things trapped in a duvet case didn't get rinsed or spun properly, I now wash duvet cases done up and the problem has gone away.
