How to Sew Binding on a Curve


Adding binding to a circular shape or a scalloped edge can be a tedious task. Traditional binder attachments for sewing machines don’t allow the binding to curve around the shape of the fabric leaving you to line up the binding by hand as you feed it into the machine. A tool we like to use to make this process faster and easier is the Right Angle Binder attachment.

This binder attaches directly to your sewing machine and carefully feeds binding around corners and curves. The Right Angle Binder works best with soft binding such as Sunbrella Acrylic Soft Braid, Sur Last, Stamoid, or other vinyl binding and is available in 3/4” and 1” sizes. Use your binder for finishing the edges of circular boat enclosure windows or the scallops along a retractable awning.

How to Sew Binding on a Curve:

  1. Install the Right Angle Binder onto your sewing machine.
  2. Feed a soft binding into the binder. Use a small screwdriver to help push the binding through if necessary.
  3. Grab the free end of the binding and pull it straight forward until you have about an inch or so of binding free.
  4. Tuck the binding under the presser foot at a ninety-degree angle from the binder. This will fold the binding in half.
  5. Using a zigzag stitch, if available, sew off a bit of the binding.
  6. Insert your fabric into the binding opening and guide it through the machine.
  7. Secure your binding at the end with a small backtack.
