A Hong Kong seam finish is a beautiful way to finish the inside of your handmade garment with a couture technique by binding the raw edges of fabric with a bias fabric. It can be the same fabric as the garment or a contrast. It is important that the bias fabric isn’t too bulky. Using the Hong Kong seam finish takes longer than using your zig zag or serger finish, but it makes the insides of your garment as beautiful as the outside!
I like using the Kong Kong seam finish for unlined jackets where you want to show a little personality on the inside of your garment! And I prefer to use a print or contrasting fabric for my Hong Kong finish.
Here is the process for a dress I made and finished all of the seams with the Hong Kong seam finish. You can optionally use a stitch in the ditch foot (shown below) and move your needle to the furthest left to sew the bias fabric to the seam allowance.
Press the seam open, then turn the bias binding fabric around the edge of your fashion fabric. The bias should be wide enough to be a scant 1/8″ inch wider than your original sewing line on the back.
Stitch in the ditch to secure the binding fabric to the back of the seam allowance.
Then press your seams open and enjoy how nice the inside of your garment looks!
The Hong Kong finish gives your garments a professional (and fun!) finish on the inside!
Here is the dress I made, with beautiful Hong Kong finish inside.
I put a contrasting flange in the primary seams on the right side of the dress and added hand embroidery stitching to emphasize the seam. The simple running stitch accents the seam lines without screaming “look at me!”
I took the extra time to do Hong Kong finish on all of the seams. As a result, the inside looks almost as nice as the right side! Check it out!

Tips for Hong Kong Seam Finish on Quilted Jacket
Making jackets and clothes from old quilts is becoming popular with all ages – not just quilters. Often the quilts already have a backing so they don’t need a lining. A Hong Kong finish to the seams really finishes off the jacket. Sewing through all of those layers and batting can be a challenge for your machine and be bulky to wear. Here are my tips to use the Hong Kong seam finish for your next quilted garment.
Cut the bias strips a little bit wider. Even though I cut out the bulk from the seam allowance, they still had a bit of batting in the seam allowance. I cut them at a generous 1-1/4″. You don’t want to cut too big, or when you turn the bias strip under, it won’t lay flat.
Here is how to do that. Sew your seam for your garment, just like you normally would. Here is how the seam allowance looks – full with batting from the two quilted layers.
You’ll want to carefully pull the two fabrics away from the batting to make it easier to remove the batting from the seam allowance. Usually just pulling with your fingers works, but you might need to use your seam ripper for a few of the stitches.
Take a small pair of scissors and begin cutting away the batting from between the two fabrics of the quilt, being careful not to cut the seam allowance fabrics.
Here I’ve been able to trim away most of this seam’s batting.
Do this on both sides of your seam allowance. See how the seam is less bulky?
Now we are ready to begin the Hong Kong finish. Take your bias strip and sew right sides together on your pressed seam allowance, making sure to have the seam free from the rest of the garment.
Press the bias strip to the outside. Turn it to the other side of the seam and stitch in the ditch.
Here is another view of stitching in the ditch.

Why is it called Hong Kong Finish?
The garment industry was very important to the growth of Hong Kong. Many of the garment pieces were sent out to sewists to add a bias seam finish to the parts before the garments was put together, thus being called the Hong Kong Finish.
Can I use store bought bias tape to do the bias seam finish on my seams?
Yes! To use store bought bias tape, you can open the fold for the first seam and then turn it to the inside for the second seam, making it super easy to finish your seams on the inside of your garment.
How should I finish the sleeve armscye seams?
You can bind the body of the garment and the top of the sleeve separately, but generally if you bind them together after the armscye seam is sewn with one strip of bias tape it will work better. Since you don’t press this seam open, the one strip of bias tape reduces bulk and finishes the seam off nicely.
What’s the difference between a bound seam and a Hong Kong finish?
A bound seam generally uses a strip of fabric cut on the straight of grain and is suitable for straight seams. Hong Kong finish uses bias strips of fabric which will easily fold around curved seams.
