Bias Binding For Scalloped Edge Tutorial

Bias Machine Binding For Scalloped Edges

Here is a small sneak peek of my latest design – Cuddles The Hexi Bear Rug! While our testing team is still working on this project, I would like to share my Bias Machine Binding technique for scalloped edges. The scalloped edges in my new pattern are formed by the shape of the bear’s ears and it’s very easy to bind them.

First of all, I should mention that bias binding is absolutely essential for finishing curved and scalloped edges, please do not use straight grain binding. Bias binding is made from strips of fabric cut diagonally at 45° angle, which makes it more stretchy and flexible.

Prepare strips for bias machine binding:

  1. Use markings on the ruler OR cutting mat to make your first cut at 45° angle. You can also fold the fabric diagonally to determine your first diagonal line.
  2. Line up the 2-1/2″ mark of the ruler with the bias edge and cut your first strip. Continue cutting 2-1/2″ bias strips until you have enough strips for the total length required.
  3. Match the edges of the strips based on the slanting direction.
  4. Holding the strips perpendicularly with right sides together, sew them along the diagonal edge with a 1/4” seam allowance.
  5. Press the seam open and trim dog ears.
  6. Fold the long bias strip in half lengthwise and press.


Cutting and Sewing Bias Strips

The binding is now ready to use. Wind it in a roll to make it easier to work with.

Roll of Bias Binding

Sew binding on the back of the quilt as follows:

Line up the raw edges of the binding with the quilt edge on the back. Leaving a 6”-8” tail at the beginning, sew the binding around the curved edge with a 1/4” seam allowance until you reach the inside corner. Stop at the center of the corner with the needle down and pivot. Make a crease on the left to straighten out the right edge, it will help you pass the corner smoothly. Continue sewing around the edge, stopping 8”-10” before your starting point.

Trim the edge of the beginning tail to make it straight. Trim the other end, overlapping it towards the beginning end by 2-1/2” (which is the width of unfolded strip). Holding the ends perpendicularly with right sides together, sew them with a diagonal seam. Fold the binding to to make sure it fits properly, then trim the corner. Press the seam open and sew the remaining part of the binding.


Clip the inside corners of the quilt edge to release tension and cut notches in the corners of the binding to reduce bulk. Be careful not to cut through the stitches.

Clipping The Corners Of The Quilt Making Notches On Binding

Finish the front side of the quilt by machine:

Fold the binding over towards the front side of the quilt and pin it around. You can pin a small section at a time or use clips instead of pins. I often pin only in the corners and then just guide the binding by hand around the curve. Sew towards the inside corner; stop with the needle down; straighten out the edge to pass the corner and continue sewing around the curve.
