Although I think the stitch holder is a good idea, I found the leather cord to be rough edged and stiff. It's difficult to thread through the stitches and its also difficult to knit the next row because the threaded stitches are very tight with the leather threaded through them. A bigger problem is that it's very difficult to get the leather into the needle edge. I couldn't get the leather into one needle at all and once I was able to get a small tip of leather into the second needle, it kept falling out as I threaded it through my stitches.
