Finish Seams without a Serger: Bias Bound Seam

For those of us who don’t have access to a serger, it can be frustrating to sew professional apparel without having straggly, fraying seams after a few washes. That’s why I’m giving you tutorials for my favorite and most versatile serger-free seam finishes! So far in this series we have covered French seams, false French seamsclean finishes, and zig-zag finishes. The last seam finish I want to teach you is a bias bound seam.

Bias Bound Seam

A bias bound seam is a very professional seam finish that leaves no raw edges and can be done without a serger. You might even notice it in high quality ready-to-wear garments (Can you tell I’m a sewing nerd that likes to examine the inside of clothes?). This technique encases the seam allowance in bias binding, covering all the raw edges so that your seams are beautiful!!

Using bias binding takes some practice and patience (I’m still working on it), but it’s so worth it! Unlike the French seam, false French seam, and clean finish it can be used on curves such as the edge of a facing or the armhole seam.


I recommend that you practice all seam finishes on a few scrap rectangles before you sew them onto a project. It might be a good idea to practice this one a little more if you are not familiar with using bias binding.

Step One:

Sew a 5/8″ seam allowance.

Step Two:

Trim your seam to the desired length. I chose to trim mine a little smaller, but not quite hide the seam stitches. You may choose to trim it so that you cover your stitching from the seam (an example of this is here) or you might want to keep your whole seam allowance.

Step Four:

Now you are going to attach your bias binding. Encase the raw edges of your seam with the binding, using pins to keep everything in place. You can also finish your seams separately if you need to press the seam open.

Using a stitch length of four, slowly and carefully topstitch the bias binding in place, being careful to catch the fold on the opposite side of your seam.

Step Five:

Your seam is finished! Press it to one side as directed in your pattern instructions.

If you get frustrated with this particular seam, don’t give up! Bias binding is one of the most difficult sewing techniques for me. The more I use bias binding and carefully practice, the better I become. Have patience with yourself and you will improve.

Love, Jess

    1. Thanks for stopping by! I often use zig-zag, but sometimes I want something else. I’d love to hear how it turns out!
