I wanted to make something that I would have been excited to pick up as an 8th-grader myself, as I remember that I always cringed at the sight of most of our books and educational materials in school because they were so badly designed (I guess/hope that it's a lot better nowadays, but still). The material is about housing today and historically, so I thought it would be nice to draw an inviting pastelly house pattern for the cover.
The pattern was then used again in a different color setting on the introductory pages, and complemented with colorful vector graphics throughout the material.
I was thrilled to hear that shortly after it was made available online for teachers across the country to order, it made it straight to the top of the list of the most ordered educational materials. It makes me so happy to know that students all over the country are learning from something I designed, hopefully not cringeing over the bad design ;)
