Why are Knit Garments Finished with Bindings Vs. Facings (And When Facings Do Work)

If you’ve ever sewn with knits, you may have noticed something curious: most knit garments are finished with bindings rather than facings.

This is a question I often receive from my customers and Sewing Circle members. So today, let’s talk about why bindings are typically the better choice for knits, and when a facing can work just fine. (As always you can listen if. you prefer - scroll to the bottom of the post for the video).

Reason #1: Knit Fabric Needs Controlled Stretch

One of the biggest reasons we love knits is their soft, cozy stretch. That stretch makes garments comfortable and easy to wear—but it also creates a challenge, especially around necklines.

A knit neckline needs to:

• Stretch enough to get the garment on and off

• Not gape, ripple, or flop around once worn

This is where bindings shine. Bindings are intentionally cut smaller than the neckline opening. When sewn on, they gently pull the neckline in, providing:

• Structure and support

• Protection against gaping

• Stretch that still moves with the garment

This controlled stretch allows the neckline to stay neat and flattering while remaining functional. A facing, on the other hand, must be cut the same circumference as the neckline. That means it can’t offer the same supportive “hug” that a binding provides which is especially important for garments that rely on stretch to fit properly.

Reason #2: Knits Are Bulkier Than You Think

While you might not think of the May Garden Jumper as bulky, iIf you compare it to a similar woven dress, you’ll notice that the knit is bulkier. Adding a facing means adding extra layers of fabric right at the neckline—an area where you typically want things to stay smooth, flat, and comfortable.

Bindings instead, use less fabric, reduce bulk, lie flatter against the body and feel more comfortable to wear. The result is a cleaner, neater neckline finish.

When Does a Facing Work on Knits?

There are situations where a facing verses a binding can be appropriate for a knit garment.

Typically, this happens when:

• The knit is more stable

• The fabric has less stretch

• The neckline doesn’t require as much support

For example, double knits or other structured knit fabrics often behave more like wovens and can work beautifully with facings. That is the case with the sweater I am wearing in the photo below.

The key is understanding fabric behavior and choosing the finish that best supports it.

Want More Help with Knit Necklines?

If this topic sparked more questions (and it often does!), I have two resources I highly recommend:

1. Get Started with Knits Mini Course

Perfect if you’re brand new to sewing with knits. It covers:

• Basic knit notions

• Fabric and pattern recommendations

• Exactly where (and how) to start with your first knit garment

• 
  

2. Exploring the World of Knits (Book + Course)

If necklines are your biggest hurdle, this is for you. It includes:

• Step-by-step instructions with photos for seven different knit neckline finishes

• Guidance on modifying necklines

• Coverage of different knit fabric types

• Bonus videos and a fabric pack so you can feel and touch the knit fabric.

Understanding why bindings are used, and when you use a facing instread, will hopefully give more confidence when sewing with knits.
