aww oh my gosh you’re adorable anon. I use whatever I have in my pencil case at school for the most part! my favorite for outlining things in black is a thin tip sharpie pen… they don’t smell and they’re really good for being precise. :) And as for making my writing look good, I just write and write and write until I like the way it turns out. Honestly writing in the margins, writing ever, writing, writing, makes you develop a sort of style. To be honest I’m still working on that myself, my handwriting changes daily. Just be creative! Use bubble letters, normal letters, contrasting colors, analagous colors, different angles, etc! And I scan things directly into my computer from my scanner and edit them on Pic monkey! I increase the contrast and play with the brightness until you can see it well :) Good luck!
