Here is a fairly common traditional darning pattern, I think.
I was playing around with this idea and some of the ideas that Sharon b had posted in her introduction to the running stitch and these ideas started flowing out. I could hear the cry, “a rather wasteful use of the thread”. I shut my ears, ran on and had a lot of fun with these.
This is a line or border version
I couldn’t bypass trying out a two way version. The red upright cross that you may barely be able to see in this photo is formed by over-stitching on the second pass.
I also wanted to try out beads with the running stitch. And so much more could be done. This was only a stab or two at that.
This is actually my favorite of the day. I’m sorry this photo is such a mess; the thinner thread for the interlacing is really a much nicer brown than is showing up here. But this is a two way pattern that I interlaced and then beaded.
