You should check out the rest of their posts/articles. I’ve ended up on them before when trying to find out the difference in the types of inks and types of pens. I have always been really impressed by the quality of their articles. Really want to give them some cash so will wander over there in a bit.
Sadly, my writing has got worse and worse since my life has become more and more digital. I should really have a goal for 2022 to be able to write legibly once again. I can’t even read my own hand writing any more - it must just be the lack of practice and it’s very sad as people used to comment on how beautiful it was (decades ago). Now it looks like a Doctor’s prescription order!
