Reddit reviews The Palmer Method of Business Writing

The two main groups of penmanship styles are Palmer and Spencierian. You can buy workbooks for both off of Amazon. Personally Spencierian is easier for me, but realize both are technically "cursive." Which I rarely use.

The book that I instead learned from was Lettering for Architects & Desginers. I realized that I always wanted my print writing to look like my mother's. She learned how to write in a drafting class. I did some research and that was the book that I found.

The 3 tips that I took to heart from my time learning Spencierian script were:

1. Slow down.: Seriously. If you do nothing else just slowing down will help a lot.
   
2. Think through every stroke. You need to make sure you have enough room to complete every letter and that all of your letters are roughly the same scale.
   
3. Practice everyday. Instead of writing "The quick brown fox jumped over the lazy dog" over and over again I copied famous passages and poems. Edgar Allen Poe, Shakespeare, the lyrics to Aerosmith songs. Pick something that interests you and use that.
   
   Hope this helps.
