What Is ITY Fabric?

ITY stands for interlock twist yarn, which is a method of putting a twist in yarn cloth to provide a more natural elasticity and softer feel. ITY knits can be made of several materials, ranging from rayon and spandex to polyester and lycra.

spandexDue to the way the yarn is twisted, you get a more natural give in this fabric than other stretchy materials, which offers a more comfortable wear and aesthetically pleasing look. The fabric is also available in a variety of colors and patterns.

How Do You Sew an Elastic Waist on a Dress?

When sewing an elastic waist, opt for an exposed seam to give your piece a cleaner look. To begin, join the bodice and skirt with a one-quarter inch seam allowance, and attach the elastic strip using a zig-zag stitch. This stitch should be positioned to allow one point of the zig-zag to overedge the elastic, while the other point enters the elastic and the seam at the same time. Completing the zig-zag stitch with this spacing prevents the edge of the elastic band from irritating your skin.
