3" Knit Elastic, White, 2 yd

I used this for a swimsuit bottom and it didn't curl at all when I stretched it, which made sewing the waistband so much easier.

This knit elastic is a dream for waistbands—it stays flat and doesn’t narrow when you pull it, which is a huge relief. The softness made it comfortable against the fabric on a pair of shorts I just finished. Exactly what I needed for a neat, professional finish.

I was worried the elastic would twist when sewing it into a waistband, but this knit version stayed perfectly flat and didn't narrow at all under tension. The 2-yard length was just right for my project.
