Susan Stinsmuehlen-Amend works with found and plate glass to create appealing juxtapositions of mundane objects. She trained as a painter but was more excited about working with glass, translating her skill for collage into the medium. Stinsmuehlen-Amend saw that art made from flat glass seemed to be limited to transparent window pieces, so she experimented with oddly colored and textured opaque glass to create compositions that could be hung on the wall like paintings.
