Tutorial: Bias Bound Seams
Bias bound seams are a simple way to finish your garment. You can easily make the insides as interesting as the outsides by using patterned bias binding or play it down with matching colors.
Either way, this is a nice finish and easily customizable. Keep in mind that the binding will add a some bulk to your garment and plan accordingly.
Today, we’ll show you two ways to finish your seams with bias tape. Version 1 binds the seam allowances together, while version 2 binds them separately so the seam can be pressed open.
You’ll need the following to create either version of a bound seam:
- Bias Binding
Version 1: bound together
1. Stitch the seams together as usual.
2. Pin the bias binding to the closed seam.
3. Sew the bias binding. Make sure that the back of the bias tape is being sewn down as you go. Once the seam is finished, press it to one side and you’re done!
Version 2: pressed open
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 little more time than version 1, since both sides of the seam allowance are bound.
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 bias tape tutorial Sarai put together!
