You can stretch your sweater by soaking the garment in a tub of gentle hair condition and lukewarm water. DO NOT wring the sweater, but after draining the sink, press the sweater against the side of the basin to drain the excess water. Remove the garment and lay it flat on a really thick towel that is very absorbent. Use another towel to blot the excess water away. Gently pull the sweater into the desired shape. Let the sweater air dry flat.

Interesting Fact: A similar procedure, called blocking, is used by high-end knit designers like St. John Knits to “stretch” garments to a larger size.
