For my first darn, I think it's not bad. Of course, there's lots of room for improvement. This method of darning, mostly suitable for small holes, is called a Swiss darn (or duplicate stitch), and, theoretically, it can be almost invisible.
I'm also in the process of (more creatively and obviously) repairing a nasty gash in a black cardigan of mine. Perhaps pictures within the next few days. Have a lovely Sunday!
