Three years ago, I bought pen-nibs and pretty wooden handles from Amazon, and started my long-lost hobby for hand-lettering and calligraphy. I also bought 3 books: Modern Calligraphy by Molly Suber Thorpe, Mastering Copperplate Calligraphy: A Step-by-step Manual by Elanor Winteres and The Complete Book of Chalk Lettering: Create and Develop Your Own Style by Valerie McKeehan.
Since then, hand-lettering became my most favourite hobby. I could do hand-lettering for 8-10 hours straight (with snacks in-between). And now, I have my own Instagram account that is still new with just a few of my recent work.
I have had one client from this Instagram and I think this is a good start!
