My original intent had been to post every lesson’s drawings here. But I quickly realised that I’m terrible enough at drawing that knowing I’ll have to actually show it to people makes me far less likely to put pencil to paper. So, I’ll only be showing the occasional drawing as I work through the 30 lessons. Also, I’ll not be doing it in 30 days because really who can find both the time and the energy every day of the week…
Anyway, here’s a pic of my work for lesson 5 – hollow cubes.
