I have three laundry baskets in my bedroom, one each for whites, reds and 'other colors'. In my house other colors are mostly blues, green and gray. When you take off your clothes, you put them in the right basket. When the basket is full I wash it. For my son, I have a couple of mesh bags, he wears white and black socks only. He puts his socks in the right color bag, when he needs them washed they go to the right basket. For my husband he has hair bands to hook his socks together before he tosses them in the basket. Most of my socks are handknits, so I toss them in the baskets loose, machine wash, but pull before drying. Privelege of rank that I don't have to mate my socks.
