The 1920s and 1930s were very fruitful: Yermylov was absorbed in ''the art of designing things'', created concepts for matchboxes and cigarette packages, took part in international exhibitions. On his initiative the Art and Industrial Institute was created on the basis of the Kharkiv Art School, where Vasyl Dmytrovych became the head of the graphic workshop. He experiments a lot with various materials — wood, metal, ropes, plywood. A French art critic once called Yermylov "the most laconic constructivist in the world'' because he was able to create a composition with only two lines.
At the same time, Yermylov met Velimir Khlebnikov, with whom they both, according to the artist, were attracted to the poetess Katerina Neymaer. For her poetry collections Vasyl created illustrations and collages. Book design was another aspect of Yermylov's art. Despite it being a massive part (during the lifetime, artist designed about 40 books), many works were lost, and this direction of his work is remembered rarely.
