Peter and Janet sort through clothes.

Tip 2: Follow the "in-out rule."

Peter and Janet tackle piles of the girls' clothes, which are scattered throughout the house. Peter says the secret is to take everything out of each room first and then sort it in a separate location.

All the clothing is placed on a tarp in the front yard. Now, it's up to Janet to sort the clothes into two categories—items to keep and items to give away. Each daughter gets a set number of bins, and once they are full, Janet must move on.

To avoid clutter, Peter says every shopper should follow the "in-out rule." Every time you buy a new piece of clothing, you should get rid of an old piece. He also makes Janet promise that she will not buy her daughters any new clothes for six months.
