In knitting, biased fabric is created by pairing increases and decreases, often at the edges of a piece, which shifts the row's stitches to the side as compared to the stitches knitted directly below them. This shift forces the rows to run at an angle, instead of horizontally.
When it comes to knitting, creating an uneven or slanted fabric is achieved by combining increases and decreases, typically at the edges of a project, which causes the stitches in each row to lean towards one side relative to those directly beneath them. This results in a diagonal orientation instead of a horizontal one.
