If you want to get more professional looking hems and neck edges, Vliesofix tape is a must. To hem, you iron the tape onto the edge, peel off the backing, turn up the edge and press again. You can now stitch the hem without it stretching.
We use the 25mm tape on most hems, and the 10mm or 6mm tape on necklines and flared hemlines where you need a narrower hem.
