The bias is the diagonal direction of a woven fabric, at 45 degrees to the threads, where the fabric stretches the most.

## In more detail

Fabric cut on the bias drapes softly and curves smoothly, which is why it is used for piping, binding and flowing gowns. Bias edges can stretch out of shape, so they often need stay tape.
