I use the "leave it in the dryer until A) I need it or B) I need to put another load in there.
Therein lies the problem. The sock monster that lives in the dryer eats them. 47 socks go in the wash, 7 come back out. As my kids grow out of socks, I am just buying all the exact same socks. Same type, same color, they wear the same size. Bam. No matching needed. Grab 2 socks and go!
