My Favourite Stitch

My poor blog has been neglected this last 2 weeks, I have been so unwell with the fatigue. It is getting worse and worse and not much grace in between. Its wham here is another one.
One thing I did do was stumble across a video on you tube, that I had lost. I thought I saved it somewhere, which I probably did, but forgot where too, or its on my old laptop.
If I put it on here, I am less likely to forget where it is.
Its a fabulous stitch, which can be used for so many other things.
