Be a smart folder

For sweaters and other non-T tops, the square fold is the way to go. Here's a quick primer: button all buttons and lay shirts face down on a bed or flat surface. Smooth away wrinkles. Fold material in at the shoulders and lay arms flat along the body so that you create a roughly two-inch overlap of material on both sides. Now fold up a third of the material from the bottom and overlap a third from the top. You should now have a tidy package worthy of any chain retailer.
