|How to Resize a Shrunken Wool Sweater|
1. Soak your sweater in a sink full of warm water. Add 2 tablespoons of baby shampoo to the warm water. Let the wool sweater soak for at least 15 minutes to relax the wool fibers.
2. Pull the sweater out of the sink and wring out the excess water from the fabric. You may want to place the sweater on a towel and roll up the sweater in the towel to soak up the extra moisture.
3. Stretch the sweater toward the correct size by pinning it to a corkboard with thumbtacks. After a few hours, stretch the sweater out again and reposition the thumbtacks. Continue this step until the sweater dries completely, and has reached your desired size.
