Yes I used a mechanical pencil, but I use very light pressure when I do upward strokes and add pressure with downward strokes. Basically trying to mimic the way you would use an old fashion fountain pen. It definitely took me a few practice runs to get into the flow.
Thank you ! That website is going to be a fun rabbit hole. Your suggestions are a great help, because I was definitely struggling with the hwesta sindarinwa and the book example you gave helped me see the shape more clearly. The pound sign is a great suggestion and one I haven’t played around with before.
