Continuous Quilt Bias Sew Easy Lesson

Follow these steps to make quilt bias from a fabric square.

Getting Started

Follow the steps below to make your own bias from a fabric square. Use bias binding for quilts with curved edges or when you want a stripe to appear to spiral, or plaid binding to be on the diagonal. Continuous bias cut 1 1/4″ wide is perfect for most curved stems and appliqué vines.


1. Cut a large square from fabric-usually 18″, 27″, or 36″. Place pins as shown in Diagram A, with 2 pins pointing out and 2 pins pointing in, to keep sides oriented. Cut square in half diagonally as shown to make 2 triangles.

2. Place triangles with right sides together, aligning sides with pins pointing in, and stitch with 1/4″ seam as shown in Diagram B. Press seam open.

3. On wrong side of fabric, draw lines parallel to long edges at intervals which are the desired cut width for bias (usually 2 1/4″ for binding) as shown in Diagram C.

4.Bring short edges together to form a tube, aligning sides with pins pointing out, and with right sides of fabric to inside. Align raw edges, offsetting by 1 marked bias width; pin, matching where drawn lines intersect. Stitch with 1/4″ seam.

5. Cut a continuous strip, cutting along drawn lines (Diagram D). Trim ends.
