I used to have my mom fix my clothes when they ripped and I was a kid and she used her machine to do it. The stitching was always this huge bulky seam. Now that I do it by hand it’s much more compact and almost invisible if I can get it to line up well. Not sure if it was some setting on the machine that could be changed to look better as I don’t have one but I like the outcome when I do it much better.
