In these artworks, I tried to create a whole visual and poetic image by applying a random pattern of threads to the text of the poem, thereby making it difficult to read. The phrases seem to be hidden behind an abstract thread net, some are barely visible. One-line poems can be read individually or combined into one long poem, where each line begins with the same words: "I don't know...". This series is an exhibition version of the artist's book of the same name.
