Practice! I found a guide for writing letter like architect, helped me a bunch, after like 30 days of learning new letter shapes

Could you post a link to this guide? My handwriting while not horrible could use some improvement, and is not helped by the fact that I am left handed.

I'm uncertain if this is the one parent mentioned, but I found this guide with a quick search: https://artdepartmental.com/blog/architectural-lettering/

This is good too! I got books from the library.
