Stitch Witchery is a no-sew hemming alternative. It is sold in rolls that resemble tape. The adhesive is activated by heat and fuses with fabric.
Stitch Witchery is marketed primarily as a time-saving alternative approach to hem, trim or belt repair that doesn't involve the needle and thread or sewing machine. It also provides individuals who cannot sew with an option for making repairs to their own clothes.
Dritz, the company that manufactures Stitch Witchery, says that the material can be washed or dry cleaned, but it recommends testing Stitch Witchery to ensure that the product meets aesthetic expectations on garments.
Using Stitch Witchery is simple: An iron just needs to be heated on the "wool" setting. The Stitch Witchery is then placed between the loose edge of the hem and the fabric. A damp cloth is placed over the area to be pressed. The iron is then pressed, not slid, against the fabric for 10 seconds on both sides. The heat activates that adhesive and fuses the Stitch Witchery to the fabric.
After the fabric cools, it can be worn as normal. It should be noted, however, that even though Stitch Witchery creates a hem, the hem does not have the appearance of the stitch work created by sewing. Some people prefer that there are no visible stitches while others find the look unappealing.
