Interlock fabric by the yard is a smooth, double-knit textile that offers twice the comfort of regular jersey, featuring gentle stretch and a soft, balanced surface on both sides. Typically 180–280gsm, it is made from cotton, rayon, or spandex blends, providing enough body for structured yet cozy garments. Its durable yet soft texture makes it ideal for apparel and casual home sewing projects.
Interlock is a double-knit construction made by interlocking two layers of knit loops, which gives it a smooth face on both sides and a naturally balanced stretch. It’s more stable and substantial than single jersey, but usually softer and more flexible than thicker structures like double knit.
Interlock made from 100% cotton feels soft, breathable, and gentle against skin, while 100% polyester interlock feels smoother and tends to keep shape with easier care. cotton–polyester blends balance comfort and stability, and adding spandex improves recovery so the fabric holds its fit through wear.
Interlock is widely used for T-shirts, tops, and comfortable dresses when you want a clean surface that doesn’t curl at the edges. It’s also great for baby and kids basics, plus pajamas and leggings where softness matters. Basics brands and children’s labels often choose interlock for its smooth feel and reliable stretch.
