I’ve never been a math person, so my 2014 purchase of a parallel glider wasn’t exactly exciting. To me, the contraption had way too many numbers written on it — seemingly arbitrarily. When I went to draw guidelines for calligraphy, though, it was love at first gloriously parallel roll! Making guidelines suddenly wasn’t a tiresome and tedious task, and slant lines could be whipped up in a few quick swipes. Seven years later, I still use the same parallel glider regularly. Today, we’ll talk about how a parallel glider can make lettering life easier for you.
