Sweaters are tricky to alter since they are knitted and not sewn. To alter them you have to introduce sewing with a sewing machine and stitches.

This way of hemming a sweater works well for sweaters with curved hems, sweaters with ties, sweaters with a split hem, and sweaters with thin ribbing.

Put the sweater on to see how much you want to shorten it.

Take that amount and minus 5/8 inch which will be the hem allowance. The remaining amount will be what you cut off.

Place the hem tape on the bottom of the sweater measuring up the amount that will be cut off. (The 5/8 inch is how tall the hem tape is.) Fuse the hem tape to the sweater with the iron. Make sure the iron is not too hot for your fabric.

If you sweater is curved you will have to cut the hem tape into pieces to create the same shape.

Once the hem tape is cooled off cut the excess sweater fabric off. Do not cut into the hem tape.

Peel off the paper backing to reveal the transparent, lightweight hem tape.

Fold the sweater up 5/8 where the hem tape is and fuse with the iron. The hem is fused in place, but it won’t be permanent until it is sewn.

Sew the hem with a twin needle. Leave long thread tails.

Tie the thread tails in a square knot.

Thread the tails into a hand sewing needle. Thread the tails a couple of inches into the hem to prevent unraveling.

Press the hem again. Wash the sweater as you normally would.

The hem tape should prevent the hem from getting wavy when I used all the tips for using a twin needle. I found that when I pressed the sweater it kind of smashed the fabric down and made it look stretched out. Once I washed the sweater it looked normal again, and it wasn’t stretched out.

I would like to hem my sweater sleeves but would keep the ribbing. Would this work for that?

The directions say to measure how long you want the sweater, and then minus 5/8″ for the hem. Shouldn’t that be plus 5/8″?
