I cut the boning and my husband melted the edges a bit with his to knife. I also wrote where they will be placed on them with the lightest color marker I had.
I sewed the bodice and pockets for the boing and slipped the boning in place.
And although after practising I think adding boning will be easier that I was anticipating, but If I have to cut different pieces I will cut them with a scissors and use nail polish to seal the edges. Sadly the bodice didn’t fit so I found more scraps to make it in the next size up. But I really like the sweetheart neckline.
