Inside/outside, plant/animal, natural/supernatural, we tend to sort the world into categories of opposition. But some things just don’t fit. It’s these unsortables that engage Susan Heideman. In her combination painted/embroidered works, Heideman tries to embody objects, forms, and entities that have characteristics of opposing categories, thereby occupying neither. Defying taxonomy, things flow, hurl, creep, or ride geyser-like spouts; auras sprout and retract; molecule-like forms mineralize; rock-like things liquefy.
