I practice calligraphy as a hobby. I mostly do western hands with a square nib. I read Arabic and tried to pick it up but gave up. It was much harder than English especially without a teacher.

A famous Western Arabic calligrapher based in the States is Mohammed Zakariya https://en.wikipedia.org/wiki/Mohamed_Zakariya. Perhaps his most popular work is the Eid Mubarak postal stamp that you can see here https://store.usps.com/store/product/buy-stamps/eid-greeting...
