My biggest project has been a fully lined wool vest with three welt pockets for Fiance. I had never sewn welt pockets before and I looked up a bunch of tutorials, decided none of them made sense and just made stuff up until I got a reasonable pocket.
It took me three tries before I got one I liked. I'm really glad that I decided to practise on cheap cotton first because the part where you cut a hole in your fabric is a bit scary.
The first one the welt didn't cover the pocket entirely, the second one I somehow managed to sew the pocket shut, but the third one come out okay and with a decent looking welt. I felt a bit like Goldilocks.
I'm pleased with how the vest turned out. It fits Fiance well too, but he didn't want to model it for photos. I made a size down from the pattern recommendations. Yes, vests are meant to button over layers of clothing, but I thought three inches of positive ease was a bit excessive. This size gave him an inch. It fits in the arm holes, but is a big snug across his stomach, so I might try grading the pattern a bit when I make it again.
I will definitely make this pattern again because it's the same one I will use for his wedding vest, but I'm going to make it out of linen for a summer weight.
The only thing I'm not happy with is one of the side seams. I think I managed to catch some extra fabric when I was sewing it up because it tucks in at the very bottom. When I look at the inside of the seam though it looks fine. I used a ladder stitch to close the lining which is so quick and easy that one of these days I might just take it out and try and fix that tuck.
All in all, both Fiance and I are happy with the vest. The welt pockets were fun to learn how to do and the vest itself was pretty quick and easy. It took me two days only because I started it at a friend's house who has such dim lighting that I couldn't see what I was doing with the black fabric so I had to stop and finish it when I got home instead.
The outer layer is 100% wool, the lining is Bemberg rayon, the pattern was originally Simplicity 2346 but I changed the pockets, and left of that tie in the back.
