How to Repair a Snag in a Sweater

by Contributor ; Updated September 28, 2017

If your favorite sweater has sprouted a big hole, you should take it to a professional for reweaving. But if it's got nothing more than a small snag or unraveling thread, you can keep the sweater from unraveling further with this simple repair.

Items you will need

  • Very Small Crochet Hook (about A Size 5)
  • Liquid Ravel Preventer
Step 1

Insert a very small crochet hook (about a size 5) from the back side of the sweater through to the front at the site of the snag.

Step 2

Use the hook to pull the loose yarn through to the back side of the garment.

Step 3

Turn the sweater inside out.

Step 4

Use the crochet hook to make a loop out of the loose yarn, then pull the loose end through the loop, creating a knot on the inside of the sweater.

Step 5

Dab the end of the loose yarn with liquid ravel preventer (sold under the brand name Fray Check), available at fabric and hobby stores. In a pinch you can use a small dab of clear nail polish instead.

Step 6

After the ravel preventer has dried, turn the sweater right-side out and gently stretch it to smooth out any bunching that the snag might have caused.


  • If you don't have a crochet hook handy, you can probably use a needle, a long, thin letter opener, or even the cap of a pen to pull the loose yarn through the sweater. Just be careful not to snag more threads or poke another hole in the sweater.
