1. Cut your pattern piece out in fashion fabric and fusible interfacing.
2. Pin interfacing to the fashion fabric. The nonfusible side is the "right" side of the interfacing so the nonfusible side will be put to the right side of the facing. We are sewing along the edge of the facing that will not be sewn to the garment.
3. Sew a 1/4" to 3/8" seam.
Check your pattern to see how much seam is allowed. You may need to clip the seam allowance on curved facing pieces.
4. Trim seam allowance with pinking shears. Since my fashion fabric was thick, I trimmed it pretty small. If you have thin fabric or fabric that is prone to fraying, you can leave a larger seam allowance.
5. Flip the interfacing open and fold it over so the fusible side is against the wrong side of the facing.
6. Fuse the interfacing to the wrong side of the fabric.
7. If there is a bit of interfacing sticking out from behind the fashion fabric, trim it off.
8. Now you have a pretty finished facing edge! Continue on with constructing your garment.
How do you like to finish your facing edges?
