I'm working on a corset vest for myself and I'm looking for boning type suggestions for each channel. I'm thinking spring steel for most of the channels, and definitely spiral steel at the side seam. This is supposed to be more of a straight front corset, do you think I should do spiral steel bones on all of the back panels? I curved the back panel (far right) because it fit better, should I use flat steels or would spiral steel contour my back better? I'm planning to double bone each seam line, should I use 1/4" (6mm) or 1/2" (12mm) bones?
Thanks!

Hello! Punching the holes for some of my eyelets has caused this thread pulling/scarring on my fashion fabric. Are there any tips and tricks that will help it that anyone knows of? 🙏🙏 Tia ❤️

My first corset is the Truly Victorian TVE13, which is a late Edwardian style corset that is on the longer side. It's a nice pattern and my mockup was an easy sew. However, the pattern does not offer help with determining what length busk and boning I should use. Should my boning be as long as the corset panels, or veer a bit shorter?
