Bias Tape

Custom Search

If you need bias tape for your project, your pattern will tell you what kind and how much you will need. As you learn to sew, you can improvise and start using notions when you think you want to change the method of project construction.


This tape is a long narrow piece of fabric cut at a 45 degree angle and comes in single and double fold. You can purchase bias binding in pre-cut packages or you can have it cut to length.

It is used to trim the edge of seam allowances, covering piping, finishing the raw edges of armholes and necklines and finishing hems. Some sewers like to finish seam edges with tape. It is more work but the result is very professional and clean looking.

I happened to be working on a project that gives example of use for bias binding. The same principle can be used for armholes, or finishing an edge of any kind. This example is finishing a neckline for a pajama set.

Finishing The Neckline

Finish the neckline using double fold bias binding. Press open one side of the tape flat. This side will be place on the edge of your project as you will see in the photo.

Pin the tape to the right side of the neck line so that the raw edges are even. Stitch in place with 1/4" seam.
