Bias binding tends to be basically a long and narrow piece of material that is usually doubled typically a couple of places.

Sewing bias binding is done on the edges of the fabric which is a technique allowing coverage of the raw edges.

This makes it more stretcher and flexible than a strip cut on the straight grain.

Hence, by attaching the strips together, a long tape is formed.

It is used for bonding the hems, interfacings to a garment, blanket, or another item such as decorating materials

This bias tape’s width usually lies between 1/2″-3″ typically depending on your kind of application.

Bias tape is commonly used in the formation of piping, binding seams, finishing raw edges, etc.

The most common usage of bias tape is to provide coverages on the edges of quilts, placemats, and bibs, usually around armhole and neckline edges instead of a facing.

Bias binding is also done for creating a simple strap for casual bags or ties clothing.

Bias binding is also perfect for handicrafts and certainly a great technique for the edges of purses and wallets.

Additional tips: the primary step is that one must be familiar with using rotary rulers and cutters in order to cut the perfect bias strips.

Then selecting the right kind of bias binding is the first thing one must identify i.e., single fold or double fold.

Moreover, for bias binding, it’s also important to decide where the bias binding is needed and how much is the required width of it.

Also, the type of binding is depended on the application. Such as, you need to opt for double binding for making a purse as the need is to show the binding.

But in another case you would not like to reveal the bias binding such as facing the neck of a dress, you might then choose single binding.

Some of the best fabrics for bias binding are mainly cotton, cotton/poly mix, or satin.

What is Bias Binding?

Bias binding is typically a narrow-like strip of fabric that is mainly cut on the bias.

Bias is essentially the grainline running diagonally across the fabric at a 45-degree angle, i.e., the need is to cut it at a 45-degree angle to the selvage of the fabric.

The cut in this manner will essentially make it stretcher and more drape-able rather than a strip cut on the straight grain.

Such bias strip can be joined for making a long bias tape that is flexible i.e., quality of bias tape. 

What is Bias Binding Used For?

Binding is mainly a strip of fabric that provides a bind in order to cover the raw edge of fabric such as it is commonly needed to bind curved sections, like a neckline.

Bias binding is also needed for finishing any seam in such a manner that it plays the role of that overlocking,

This is to stop the stitching edges of fabric from fraying, thus offering strength and durability to your clothing.

Commercially, these Bias-cut strips of fabric are having the purpose to offer an appealing coverage to raw edges of the fabric

And also to make piping for pillows and for sewing applications.

When Do You Need to Sew Bias Binding?

You can essentially sew bias binding with a single fold because in this way the binding appears on one side of the fabric’s edge.

In another case, you can also sew bias binding so that half of the bias binding will appear on each side of the fabric’s edge.

If you are sewing bias binding along an edge where the two ends will meet, then you will also need to join the ends of the bias binding to complete your project.

How to Sew Bias Binding (Tips)?

  1. Chalk the fabric where you desire to sew the bias binding.
  2. Then cut fabric strips on the bias, at a 45-degree angle to the grain of the fabric. 
  3. Just rotate the folded fabric so that the folded edge is parallel to your cutting mat rulers.
  4. Using your straight edge and rotary cutter, then cut perpendicular (90 degrees) to the folded edge to create your strips.
  5. Connect short strips together at ends if you need longer strips.
  6. Trip excess seam allowance
  7. Simply Pin the bias binding to the fabric
  8. The need is to sew lengthwise the crease of the bias binding. 
  9. Press the binding over the seam allowance with low iron.
  10. Fold the bias binding over to the other side of the fabric.
  11. Iron the seam to flatten it.
  12. Lastly, simply sew along the other edge of the bias binding.

Now you’re ready to fold, press, and sew according to your pattern’s instructions!
