Really enjoying all your lessons, you are a amazing teacher and player.
I was just watching your video on the harp harmonics and you mentioned using one finger to fret two strings, i've also seen videos where Tommy Emmanuel has mentioned doing this but i'm kind of unsure how you are both doing this.
Is there anyway you could do a quick 1min close up of how your fingers are placed for this/ when you usually would want to use this. Are you using the tip of your finger in the middle of the two strings to fret it? I don't get it!! Any help for this would be great
