The boning for the stays will be sandwiched between two layers of fabric, the exterior Toile layer, and an interior denim layer. The edges will be bound with navy bias binding.
The denim was purchased for a quilting project because it was lightweight and the perfect indigo. When I had difficulty getting a needle through I took a better look at the fabric and saw it had a super tight, super small, herringbone weave. I thought, hmm, this might work well for a corset.
I already have thread to match both the off-white of the Toile and the blue of the denim so off we go.
