Making Continuous Bias

Have you ever heard of continuous bias? I first learned about it from a customer at Fabricville where I no longer work.(But I really enjoyed my 6 years as a part-time worker).

I also have to acknowledge Sandra Betzina and Ron Collins because their Web TV Show clarified the process for me.

1. You start with a square of fabric.This one was 15"square.

2. Draw a line to join two corners on the diagonal.

3.Cut the square in two along the diagonal.

4. Bring the two triangles together right sides of fabric facing each other.

There should be two little triangles sticking out at each side.

5. Sew with an exact 1/4" seam.

6. Open up the piece and it should look like this. Press open the seam.

7. Draw lines 2' deep.(You can make them wider if you want but you'll end up with less product.Don't worry if your last strip is a little more than the 2".Just trim off the excess.

8. Fold your piece so it looks like this and your lines are lined up.It took me some time to figure this part out.

Now this step is a little hard to explain but bear with me.

9. Move the bottom half over to the left until the first bottom strip lines up with the second strip in the top half.

10. Now you're going to pin the two halves together from this point. When you pin, stick the pins in so you will have a 1/4" seam but your bottom and top lines half to intersect so stick the pin through the bottom line at 1/4" and then through the top line at 1/4" like this.

Notice the shape of your fabric now.

11. Now sew the 1/4" seam across the joined lines. Press the seam open.

Notice how the lines of each half line up nicely.

12. Begin to cut along the lines being sure to cut only one layer at a time until you reach the end of your fabric.

Believe it or not,but that little 15"square of fabric will yield you about 96" of bias strips.

Now you can go ahead and prepare your strips in whatever way you prefer. This is what I do.

I truly hope this is clearly explained and that somebody can use this in their sewing projects.Please let me know what you think.


  1. Thank you for the tutorial. I will try this very soon.

  2. Wow. I have been sewing for many years and this is the most detailed instruction I have ever seen. Great job!

  3. I just found this. Why didn't anyone tell me about it. This will help so many people.

  4. I forgot about this. Thanks! You did a great job with the pictures and the explanation. I am bookmarking this post! :)

  5. Oh, my goodness! How much easier is this than the way I have done it - cutting first and then sewing each piece

  6. Love this, why didn't I think of doing it this way before? Thanks for tutorial!
