You have the choice to bind the seam allowances together, or bind them separately. Consider the thickness of your fabric, where the seam is located in the garment, and what style you desire. For this tutorial, I will demonstrate how to sew them separately.
If you are applying a bound finish to a curved seam, cut your strip on bias. If you are unfamiliar with the terms: grain-line, crossgrain and bias please click HERE to learn.
Its best to use light to medium weight 100% cotton for the binding tape.
