Cooped up at home and isolated from dear ones, this year has been all about facing our feelings. But sometimes, it can be difficult to find the right words to express ourselves, says city-based analog collage artist Kanika Agarwal. It can be helpful, instead, to visualise those thoughts, find their echo in letters, words and images in newspaper articles, magazine pages, medicine bills, order invoices, manuals, and turn them into a collage, explains the artist, who is hosting a workshop revolving around the art form, titled Sing songs of the self.
