My teen began lettering onto paper this Summer, and her interest sparked my own again. I used to sit bored in class, writing the alphabet and my name and future baby names (Brenden Schaad and Brittany Annelie - both partially used on future babies, and Savannah - not used at all).
Lettering is easy because any scrawl is art. I like to write the alphabet in caps and in lowercase in different fonts that I think up. If I like a font, I combine letters to make simple words like "no" and "home", to connect the font and see how it looks. Then I write full quotes or phrases.
Honestly, it is easy. It will look wonderful. And you'll feel more relaxed because of it. Try!
