How to Rework a Loose Collar on Hand-Knit Sweaters

Materials & tools you'll need

Step 1 — Rework the collar

If your collar looks too loose or generous, the culprit is often an incorrect needle size used during knitting. The fix is to frog (unravel) the collar section — pick up stitches all around the neckline using your knitting needles, carefully remove the old stitches, then rework the collar using Knit One Purl One ribbing for approximately one inch. This tighter stitch pattern brings the collar in and gives it a neat, professional finish.

Step 2 — Close the armpits

Open underarms can compromise the look and fit of your sweater. Use the Kitchener Stitch to graft the live stitches on each side of the armhole together, closing the gap seamlessly. This technique creates an invisible join that blends into the surrounding fabric without any bulk or visible seam.

Step 3 — Weave in all ends

Before blocking, track down every loose yarn end throughout the sweater and weave each one in securely using a yarn or sewing needle. This step may feel tedious but is essential — it maintains the structural integrity of your work and ensures the sweater holds up through wear and washing.

Step 4 — Block and try on

With all ends woven in, it's time to block. Soak the sweater in warm water with a wool wash such as Yukaland, then gently squeeze out the excess water. Lay the sweater flat on blocking mats and use blocking pins, knit blockers, and T-pins to ease it into the correct shape and measurements. Allow it to dry completely, then try it on — blocking evens out the stitches, improves the drape, and ensures the perfect fit.
