What are you most proud of? The speed with which I was able to make this vest. My son was very happy with it. I considered it to be more of a muslin (practice), as I had never made a man's vest before. I do need to practice welt pockets a bit before proceeding to better fabric. What advice would you give someone starting this project? Study tailoring techniques. I was not too pleased with the way the lining went in (sew lining to outer layer with right sides together, turn, then stitch shoulders together). This left way too much room for error in my opinion. The couture way of hand-sewing the lining seems much better to me.
