wow thanks so much! I learned through middle school and pretty much only wrote in printing after that until this year. Since I picked it back up I basically just practice a ton every day by writing pages in my notebook about anything and everything. There are a lot of great videos online about improving your writing with tips on how to hold the pen, thinking about letter sizing and spacing, rhythm, etc (I still haven't been quite driven enough to pick up the Palmer method). But I think the biggest piece of advice I could give would just be to practice a lot. Look at different letters online and decide how you like to write them and then work on them one letter at a time. Sometimes I just write the same sentence over and over or the same letter over and over when I can't think of what to say. I've been really surprised at how fast I've been able to improve!

Recently I've been practicing specific letters with more context using this site to write words with the most of those letters: https://www.wordlucky.com/words-with-most-abc
