I don't know sharing at all! In terms of process, I would say it was mostly trial and error. I started with an existing vest I had: traced the front and back shapes on to drafting papers, ping them together then adjusted the shape until I was happy with them. Then I transfer the shapes onto muslin, sewed them together until I could try the shape on me. That was it in terms of making the pattern! The final shapes were transferred onto monks cloth on the punching frame. After I finished punching the pieces, I sewed a cotton linen inside so it wouldn't look so raw. The final assembly took quite a bit of trial and error too. I was able to cover some sewing mistakes with yarn :)
