Here are some shots of Muslin #2. I've made several small changes, and I think things are looking good so far.
I'm actually deviating from Cabrera here because he doesn't include sleeves in the muslin fitting. The body of the muslin jacket is adjusted, if necessary, and the shoulder width is checked. Then he moves directly to the fashion fabric. The jacket, complete with its interfacings, pockets, shoulder pads etc., is basted together for its first fitting and additional adjustments. Once everything looks right, the sleeves are drafted to fit the jacket. All of this seems a bit overwhelming right now. It may be WAY beyond my ability. For now, I'm just planning on extra wide seam allowances and hoping that the linen's weight will hang better than the cheap muslin.
