All elastics are made from a rubber base, which is bound and strung with an outer coating of fabric. The density of the rubber within as well as the thickness and strength of the outer fabric is the defining difference in what type of elastic works best with various projects. Knowing the types of elastic that exist will help you to pick the right one on your next craft-shopping trip.

Braided Elastic
  • Braided elastic is narrow and is woven in such a way that when it is sewn through, the extent of the elasticity is somewhat interrupted, so that the string conforms to the shape of the material around it. This is ideal elastic for sewing shirt sleeves, swimsuits and other clothing that needs some degree of stretchability without being overly clingy. Braided elastic is created with lengthwise, parallel ribbing to preserve the material's ability to stretch.
Knitted Elastic
  • Typical clothing such as shirts, dresses and other naturally-fitting fabrics need knitted elastic for sewing. This lightweight elastic is not greatly affected by the piercing of a sewing needle, yet it retains the shape of the clothing article. Knitted elastic is literally created through a knitted cross-over pattern, just as sweaters and other yarn-type material are made, except that knitted elastic has a rubber base.
Woven Elastic
  • Woven elastic is a very sturdy, thick and strong elastic ideal for heavyweight fabrics such as furniture, car seat covers, handbags and other thick material that needs a durable combination of sewn binding. This elastic is created with stitches going both lengthwise and crosswise, so that it is very difficult for it to break under pressure. These elastic tapes can be used for a variety of applications such as in undergarments, sportswear, leather garments, luggage inners; seat covers (Car) etc.
