How To Cut a Bias Binding

Bias bindings are used in finishing off quilts or other similar linen materials. This seals your work and helps you avoid the fraying of your fabric. Applying bias binding can be time consuming but in the end, it is there to protect your well-made quilt or comforter. After a little practice, making your own bias binding can be an easy and repetitive task.


  • Rotary cutter
  • Strips of fabric for the binding
  • Long ruler or a T-square
  • Sewing machine or a basic sewing kit
  • Pins
  • Sharp scissors
  • Cutting board


  • Selecting your fabric. Get a fabric that compliments your project. It does not have to match your actual fabric. As a matter of fact, contrasting bindings and fabric make a good combination and “frames” your quilt very well. You can also use strips or scraps of fabric for the binding. Cotton fabrics work best since they are not that slippery and would be relatively easier to work with as compared to satin fabrics.
  • Cutting it into squares. You should then cut your fabric into perfect squares, the size of which would depend on your project size. As an example, a quilt or comforter that is around 108 x 80 inches in size should need a 33-inch piece of square fabric.
  • From squares to triangles. Now that you have your squares of fabric, make each square into 2 triangles. You can do this by cutting the square diagonally. If you have a rotary cutter, this should be fairly easy to do. A pair of sharp scissors and a t-square or a long ruler should also do the trick. It is very important to have the triangles at equal size.
  • Sewing the two triangles together. Sew the two triangles together at their shorter edges. This would mean that the area where there is a right angle of both triangles should be sewn together. When you unfold the piece of fabric, it should look like a parallelogram. To help you flatten out the piece of fabric, iron it open. It is best to have all of your square pieces cut and sewn together so that you can just iron them all out in one go. Laying out your pieces of fabric on a table to resemble parallelograms would also work if you are a bit confused on how to piece them together.
  • Marking the fabric on the wrong side. You now need to mark the fabric on their wrong side with the t-square or a long ruler with tailor’s chalk. If you do not have tailor’s chalk, ordinary chalk or a lead pencil would also do the trick. The lines should be 2 and a half inches apart which should run the entire length of your fabric.
  • Making a tube. You then need to make a tube out of your fabric. This can be done by putting together the short ends of your textile. Make sure that when you do attach them, the right sides are showing. The first marker that you drew should be offset, making some sort of extension.
  • Finishing it up! Hold on to the protruded piece of fabric and start cutting away continuously through the entire length of your fabric. Follow the chalk marks that you initially drew. Piece all of your bias strips together and once you are done, you now have your binding that can be used as a frame for your quilt or comforter.

Making the strip can be a bit time consuming but at the end of the day, the effort should be worth it. Remember to make use of cotton or other similar material so that sewing the piece together will not give you a headache.
