Very,very nice, Robin! Looks like you had the forearm of your strumming hand anchored down on the arm of the sofa. Did it keep you from drifting? Looks like a great way to keep the elbow from falling.
Now that you mention it, it does look that way doesn’t it. It certainly wasn’t intentional. I was sitting at that end of the sofa because it is closer to the fire so it is warmer. I certainly don’t need to rest my arm on the arm rest.
