Did a Skillshare course as the last part of my physical portfolio for uni. Began the concept last night and finished just now.
Based on The Daily Drop Cap project that became a series of classic releases by Penguin, Jess Hiche was super insightful and I highly recommned this course. Though I will say you probably need to have your head around a bit of type and illustrator already.
My project was based around the book I'm currently reading; The 4-Hour Work Week by Timothy Ferriss. He talks about not doing useless time wasting, and helps get results without doing what's expected of you, and I used that as an analogy for my letterform.
