But that doesn’t mean you have to get rid of your favoritesweater.

Doing so can cause the snagged thread to begin to unravel.

Never pull on the sweater, either, hoping the extra thread will just disappear.

Instead, correctly repair the snag as soon as possible so it doesn’t get worse.

Leave the hook slightly open so it’s possible for you to capture the snagged yarn.

Be patient, and try not to make the hole any bigger.

Smooth the Pulled Threads

Now, turn the sweater inside out.

Gently pull the knitted fabric if the site of the snag is rippled.

With gentle manipulation, some of the snagged thread will often ease back into place.

Allow the nail polish to dry completely before you turn the sweater back to the right side out.

Gently smooth, tug, or pull the knit back into shape.

If the sweater still looks rippled, use aclothes steameror asteam ironto smooth the fabric.

This is done on the “wrong” side of the fabric to better hide the fix.

Fraying knit cuffs can be challenging to fix, however, because it is likely more than an unraveling.

Also, look for fabric stabilizers, liquid seam sealants, and fabric glues that halt frays.

If your sweater shrank, it’s possible to restore its shape.

To do so, you’ll need to wet the sweater and then block it back into shape.

Blocking a sweater involves pinning it to a surface to reshape it while it dries.

If the sweater has not shrunk but looks misshapen, you might still use the blocking method.

Sometimes a crochet hook is too large to repair a snag in finer knits.
