How to add side boning to a bra?
1. Lay your boning on your the side seams and mark off the length you want. Make sure to leave some room above and below the boning to close the channeling. Then cut.
2. Round off the ends of the boning with a nail file. This prevents sharp corners from poking through. You can also use your scissors to created rounded ends on the plastic.
3. Now it’s time to add your channeling. Line up the channeling so that it is centered over your side seam and stitch down each side, leaving the ends open.
4. Insert your bones and test the length. Do you have enough room to close off the channeling with your machinef foot? If not file or cut a bit more off the ends.
5. Close off the ends. I stitch forward and backward with a small-length straight stitch.
