Earlier we did a tutorial on bias bound seams. Here is another bound seam, this time pressed open. Usually this finish is found in jackets or garments made with thicker fabrics such as cotton twill, certain wools or other medium to heavy weight fabrics. Whatever the garment, the seams must lie flat so make a test seam if you’re using a thick fabric.
This seam is fairly easy to make but takes a good amount of time since both sides of the seam allowance are bound.
- bias binding
1. Sew the seam as you would normally.
2. Press the seam open.
3. Pin a strip of bias binding to one of the seam allowances.
4. Sew the bias binding, being sure the binding is sewn on the back side.
5. Follow steps 3 and 4 for the opposite seam allowance.
6. Press the seam open.
The seam will remain open on the inside of the garment. Play around with different bias bindings. Make your own using this easy tutorial Sarai put together!
ETA: Thanks to readers for pointing out some naming confusion between blound and Hong Kong seams. The post has been corrected for clarity.
