The cola can pen remains one of my favorite writing instruments. It is capable of so many things, from rough to smooth, from thin to thick, from splattered to refined. I will show you how I use the pen and then define some principles by which you can develop your own gestural scripts without imitating other calligraphers. Script is, after all, a very personal form of expression. But finding your own voice is not always easy when there are amazing posts on Instagram every day that might exert a powerful influence over your work. We will look at this problem very closely and see how you can create your own gestural style.
