How to Fix a Snag in a Sweater or Knitted Fabric

Snags happen, especially on knitted fabrics because of the looser yarn structures. Then snags become holes. Learn how to save your favorite sweater and how to prevent snags from happening.

First, never cut off the snagged thread or use a sweater shaver or razor to remove the thread! Those actions can cause the snagged thread to begin to unravel. Never pull and tug on the sweater hoping the extra thread will just disappear. Instead, make the repair correctly as soon as possible so it doesn't get worse.

Sweaters are prone to snags because of the nature of knitted fabrics. The threads float over each other and some are loose enough to snag and pull. Sometimes a snag will make a hole but often the snag just leaves an ugly, dangling thread. But with just a couple of tools and a little time, you can save the sweater, blanket or jacket for many more years of wear.

All you need to repair snags is a small crochet hook (size 5 or smaller) and clear nail polish. You can also use a large blunt needle to push the snagged thread to the wrong side of the sweater.

1. Start by inserting the crochet hook from the wrong side of the sweater through to the front side of the fabric or sweater at the snag. If you don't have a crochet hook, create one by straightening out a paper clip and creating a small hook at the end.
2. Use the hook to pull the loose thread on the front of the fabric through to the back side of the sweater. You can also push the snagged thread to the wrong side of the fabric using a large, blunt needle. Be patient and try not to make the hole any bigger.
3. Now, turn the sweater inside out. Gently smooth the knitted fabric if it is rippled. With gentle manipulation, some of the snagged thread will often ease back into place.
4. Use the crochet hook to make a loop of the loose yarn. Pull the end of the yarn through the loop to create a small knot on the inside of the sweater. Again, don't cut the thread; just tie a knot to hold it in place on the wrong side of the fabric.
5. Dot the knot and any cut ends of the yarn with a tiny bit of clear nail polish. Allow the nail polish to dry completely before you turn the sweater back to right side out.

• One of the easiest things you can do to prevent snags on knitted fabrics is to do a better job of sorting clothes before you wash them. Never wash a knitted garment with heavy jeans or clothes with zippers and studs that can snag and pull threads. If you must do a mixed load, protect knitted clothes by putting them in mesh laundry bags before placing into the washer.
• Skip the washer completely and hand wash sweaters instead. It is important to wash and dry sweaters correctly.
• Always remember to fold your sweaters rather than hanging them to prevent stretching. And be sure your dresser drawers are smooth or lined with acid-free paper to prevent snags.
• Check surfaces at work and home for abrasive edges that can snag fabrics and cause small holes that washing makes more evident. Have you gotten a new table, desk or countertop? Improperly installed granite or stone countertops have a bad reputation for snagging clothing.
• Is your clothing catching on belts, zippers or pant closures while you wear it? Check suspected culprits for rough edges. You may be able to smooth surfaces with a metal file or sandpaper.
