First I outlined the pieces by stitching around the edges through all three layers. After they were outlined, I stitched the boning channels.
Then I boned the channels.
I turned under the center front and center back edges and made the lacing holes.
Then I turned under the seam allowances and whip stitched them down.
I joined the pieces by whip stitching, covered the seams and started binding the stays.
I finished the binding an added shoulder traps.
The last step was adding the lining.
