I started doing calligraphy and lettering a couple years ago after I received The ABC of Custom Lettering by Ivan Castro for Christmas. I practice a lot. Although, not so much in the warmer months because I spend a most of my free time riding motorbikes. Now that there’s ice on the roads I’ll spend some of that time doing lettering and calligraphy. The rest will be spent on the endless, and sometimes overwhelming, task of learning and keeping up with web development.
One thing that’s helpful is having a guidelines sheet under the paper I’m writing or drawing on. Making guidelines sheets isn’t hard, but it is time consuming. I need different ones depending on what scale, nib width, paper size, or slant I want to use. I used to make them in Illustrator, but that didn’t save much time. I tried some online generators but the output had too much cruft and I’m picky. They also took a long time to generate. So, I made my own guideline maker using DrawBot. It’s fast and simple. The user interface needs some work.
I also wrote a DrawBot script for calculating the Natural Layout Formula from Mastering Layout: Mike Stevens on the Art of Eye Appeal. I may never use this but I got idea of doing it stuck in my head so I had to make it. That is also on GitHub.
