Can someone double check my brain?
Say I'm sewing a set of stays that has three layers. Two are a heavy/mid weight for holing boning, and the top layer is a thin fashion fabric.
With this, do I sew all three layers together, keep the fashion layer flipped up as I sew all boning channels, and then add boning. Flip down fashion layer and sew along bottom edge to seal channels, then add bias tape? (I sew all bias tape by hand)
Or do you typically sew the two layers for the boning, finish all of that, then sew on the outer fashion fabric layer and then bias tape? It's my first time doing one with a fashion layer not stitched with the boning channels.
OR do I just go ahead and stitch through the fashion fabric? I was going for a smooth outer look if at all possible.
**This is for a costume but it is a structured pattern. I've had a migraine for a week and cannot think straight but my event is in ten days and I need to get this done.
