Most of Minyintiri's paintings are done using synthetic polymer paint on canvases. His earliest paintings were done on paper. His paintings are almost always multi-layered (several layers painted over the top of each other), with strong motifs and symbols representing landmarks or figures. Each layer represents a different memory or story. Because of his old age, Minyintiri only paints six to eight artworks a year. Nearly all of them are large canvases.
