How to make a continuous bias binding

by Satomi Hoar

Do want to learn how to make a continuous bias binding without the fuss of joining countless strips? This nifty technique becomes your sidekick when dealing with generous amounts of bias for quilts or other exciting sewing ventures. And here's the best part—it's a time-saver!

Recently I had to make bias binding for my projects and took some photos of the process. I'm going to share how I made a continuous bias binding from a square fabric.

Prepare a square fabric; the one I used in the photo was 18 inches square.

Cut the fabric in half diagonally.

Take the right end of the cut triangle, with right sides together, place it onto the left end of the other triangle.

Secure with pins and sew the pieces with a 1/4" seam allowance. Press seam open.

Use a pencil to mark your desired binding width; in my case, I chose a 2 1/4" width for the binding.

If the right end of the piece is too narrow, trim it (as shown in the above photo).

Now, match both ends together and pin to secure, but offset the drawn lines by one strip. Ensure that the drawn line remains continuous.

Pin onto both drawn lines 1/4" away from the edge.

Note and tip (added on 1/11/2024): After sharing this tutorial, I realized the importance of clarifying this particular step, as it can be tricky. It occurred to me later that drawing the line 1/4" away from the edge makes it easier to identify the points where I need to pin.
