Tip #1 - Stop folding stuff that will be hung up later!
If you are hanging up shirts, lay them flat in a pile. This will also make it easier to put hangers in them later (see below).
Tip #2 - Fold pants according to owner.
Make piles for each person in your home or at least for each room. Makes it so much easier to put away when you just got to plop a stack of clothes into a drawer.
Tip #3 - Throw all the socks in a pile. Match them up last.
Socks have a way of getting stuck in pants, so just throw them all in a pile and save them until the end and you'll *hopefully* have a match for everyone.
