But you can still clearly see the cloth edge inside the buttonhole, which looks odd to me.
Sorry, I reread this and I missed your point before. IME when one cuts between the stitching there is very little or no visible cloth inside the hole. If there is, one can turn the hole out and with a very
sharp pair of scissors carefully trim right up to the stitching. In most cases, there is a defined valley between the rows of stitching, and not enough cloth within it to show once cut. I just pinched myself, and confirmed that yes, indeed I am debating/discussing lapel buttonholes. I will now shut down the browser and leave the house.
