How to Make Bias Tape

Learn how to make bias tape the fast way! So simple and your binding will turn out perfect every time!

If you’ve ever tackled a quilt with those tricky curved edges, you know the challenge of finding the perfect binding to finish it off smoothly.

Enter the game-changer: making your own bias binding.

It’s the secret ingredient for wrapping up those curves neatly, ensuring your quilt looks as polished on its edges as it does in the center.

I’ll will walk you through the surprisingly simple steps of creating bias binding from scratch.

Not only does this method give you the flexibility to match your quilt’s fabric perfectly, but it also adds a custom, professional touch to your project.

Whether you’re a seasoned quilter or just starting out, mastering homemade bias binding is a skill that will elevate your quilting projects to the next level.

On Tuesday I shared this tutorial on how to transform a sweater into a cardigan using bias tape as bias binding on all edges and as a closure (ties).

Did you know you can make you own bias tape? There are a few different kinds of bias tape (one fold, double fold, etc.) and a couple of ways of making them. Since we need double fold bias tape for the cardigan I thought I would share with you how to make it.

The method I am showing you today is on how to make a continuous strip of bias tape from one square of fabric!

All you have to do is sew two seams and then cut around and around until you end up with a huge strip of bias tape!

What is bias binding and why use it?

Bias binding is a strip of fabric cut on the bias (at a 45-degree angle to the weave of the fabric) which makes it more flexible and stretchy. It’s used to finish the edges of quilts, especially those with curved edges, because its stretchiness allows it to conform smoothly around curves and corners.

How much fabric do I need for bias binding?

The amount of fabric needed depends on the thickness of your binding and the perimeter of your quilt. A simple formula is to calculate the total length of binding required and divide by the usable width of your bias strips. There are also online calculators and charts that can help you estimate the fabric needed.

Can I use any fabric for bias binding?

While you can use almost any fabric, 100% cotton is preferred due to its durability and ease of handling. Lightweight to medium-weight fabrics work best, as they’re easier to fold and sew without becoming too bulky.

What’s the difference between bias binding and straight grain binding?

Bias binding is cut on the 45-degree angle to the fabric’s weave, offering more stretch and flexibility, making it ideal for quilts with curved edges. Straight grain binding is cut parallel to the selvage or weft threads and is best suited for quilts with straight edges due to its stability and less stretch.

Materials Needed:

fabric of choice (woven cotton such as quilting cotton)
cutting mat, cutter, scissors
pencil or tailor’s chalk or washable ink pen
hem tape maker

How to make a continuous strip of bias tape:

1) Start by cutting your fabric into one perfect square. I started with a 18×20” fat quarter so I had to cut it to a 18×18” square.

2) On the wrong side of the fabric trace a diagonal with a pencil or tailor’s chalk, from one corner to the other, using your ruler.

3) Cut along that diagonal.

4) Place the two triangles right sides together as shown on the image. Pin and sew with a 1/4” seam allowance (SA).

5) Press the seam open.

6) On the wrong side trace parallel lines that are 2 inches apart, using a tailor’s chalk or a washable ink pen.

7) Turn the fabric piece with right side up and fold both upper and bottom edges to the center as to form a square, with the lines matching at the diagonal center edge.

8) Pull the upper left tip to the left until the lines move one line to the left (they will now be re-aligned with the next line).

9) Grab the two diagonal center edges and place them right sides together. Pin and sew with a 1/4” SA.

10) Press seam open.

11) Start cutting along the lines all the way until you go around and around through all the lines in a continuous cut.

12) You’re done!

It is not that hard, isn’t it? I love to make my own bias tape, this way I can choose exactly the color or print that best match the garment I am making. And the best thing is it really doesn’t take much fabric! I used a 18×18” fabric piece and ended up with almost 2 yards of bias tape! I will be back soon with another apparel sewing tutorial and hints & tips. In the meanwhile you can stay in touch over Made by Sara.

FREQUENTLY ASKED QUESTIONS:

What’s the best way to store bias binding?

Bias binding can be stored by rolling it around a piece of cardboard or a bias binding winder. This keeps it neat and prevents it from becoming tangled or creased.

Can I make bias binding without a bias tape maker?

Yes, you can. After cutting your strips, you can manually fold and press the edges to the center and then fold again to create the binding. It’s more time-consuming but doesn’t require special tools.

How do I calculate the bias binding width?

The width of your bias binding depends on your project and how wide you want the finished binding to be. A common width is 2 1/2 inches before folding, which finishes to a 1/4 inch visible binding on the front of the quilt.
