Cut the sweater down to the size that you want your sweater bag to be.

Lay the sweater out on your work surface, and cut a straight line across under the arm pits to divide the sweater into two. Toss the top portion of the sweater aside for use in a later step. For now, you'll be working with the bottom portion of the sweater, which will serve as the body for your sweater bag.
