For several years I have been thinking about the design of a type family that explores, on the one hand, the modernist aesthetic that we know, from the Alphabet "a.r." designed by Władysław Strzemiński, and on the other, to the multiscript pre-war Warsaw. This is how the idea of creating the Polin Sans typeface was born. After researching on geometric variants of the Cyrillic alphabet, I was inspired by the text "Towards an open layout: A letter to Volodya Yefimov". I was intrigued by the fact that circular forms, which we are mostly familiar with in the Bulgarian Cyrillic, can be implemented in the classical version, without disrupting the reading process.
