Snags
Fix a snag or loose thread in a sweater by turning it inside out and using a simple safety pin or needle to grab the snagged yarn. Then pull the excess yarn back into the inside of the sweater. Knot the yarn inside the sweater (as close to the fabric as possible) and trim off any of the excess.
Want to prevent snags in the future? Clothing experts warn that one of the easiest things you can do to prevent them is to do a better job of sorting clothes before you wash them. Keep your knitted garments away from jeans or other heavy clothes with zippers, which pull threads. Also make sure pet nails are trimmed and smooth.
