Non-Dominant Hand Month
Around 2017 I had the pleasure of being taught construction drawing by Peter Han. Among other things, Han showed us that he draws with his non-dominant hand for a month every year to train himself.
I took this idea to heart and decided that February was going to be the month I would draw with my non-dominant hand every year! That same year I made a 10 page comic almost entirely done with my right hand (I'm left handed), except for the panels and lettering.
