I bought some really big ziploc freezer bags (about 12" square - not all grocery stores carry them so you may have to look around). I then sorted out all of my controllers and extensions by platform and stuffed them into separate bags - I didn't bother labeling them since it is pretty easy to spot the type you need by looking in the bag - but it would be easy enough to do that if you wanted. I also bought a box of rubber bands and got the cables in each bag to stay untangled.
