My buttonhole foot keeps getting stuck in the jacket, leading to *lots* of frustration. I dont have problems in scraps, so it's something about the bound seams and collar getting in the way of the feed. It stuck in the middle of buttonholes, got confused and couldn't finish. I was left with half finished buttonholes! One I unpicked, but I think that affected the fabric integrity. So the next time, I finished the but to hole freehand with a tiny zig zag stitch. One came out fine. A second I needed to "help" the machine feed and that looks OK. The other two that I had to finish myself look pretty crappy. It's very disappointing because the jacket is otherwise lovely - flat felled seams, bias bound seams in pretty florals, pretty nice top stitching, etc. Does anyone have tips for doing the buttonholes on this jacket?
