Kerning video below:
Those are very useful videos. Too bad I can’t understand it, but I know what you are doing 
Thank you Erwin,
sure you know what I am doing 
I was motivated by some guys to make those videos, because of rare videos related to open type features in Arabic.
Do I recognise a little Bainsley in there ? 
I like it, l allowed to myself use Bainsley Font if you don’t mind
Of course I don’t mind, that is what its there for. I’m delighted to see someone is using it.
Great 
, Thanks PJMiller
