I made a sweater for my husband. Before I started I checked the gauges and adjusted my needle size accordingly. I followed the pattern for the specified size and the finished measurements were correct, but the sweater ended up being too big. The chest measurement on the pattern was for 57 inches. When I washed it, I measured it and it was 66 inches. Is there something I need to know about the difference between finished garment measurements before it is washed and after?
