Ida Helen Jarvis came up with the idea of making pictures out of feathers. She would travel around the world, visiting zoos and aviaries to add to her feather collection. Then she would arrange the feathers to form pictures of landscapes, gluing or stitching the feathers onto a cardboard mat.
She was so taken with this idea that she decided to patent it (Patent No. 1,395,575, 1921). Included in her patent was the idea of using down to represent foam in a stream of water.
Her feather paintings must have been quite colorful. But unfortunately the only image of one I can find is the black-and-white drawing included with her patent.
