Pre-sort laundry with a Triple Storage Bin
Among the tips in a recent 43folders excerpt of "Everyday tips from MonkeyFilter" was one that recommends pre-sorting laundry as you take off your clothes, so you don't have to sort it as you put it in the machine.
We've been doing this for years using a Triple Storage Bin, and it works great!
Pre-sorting really does make doing laundry a lot easier, since you just grab the appropriate bag (colors, whites, etc.) and toss it into the machine. If you have the space, this triple storage bin is a good way to do it.
