Herbarium. Leaves have been collected by botanists and botanical artists, as well as tucked into books by the rest of us, for centuries. They offer us a closer look at nature, offer a way to decorate our homes, and remind us of days gone by. Printed on Moenkopi Unryu paper, which is handmade from natural mulberry and hemp fibers using the traditional Japanese Washi techniques. The strands of plant fibers show in the paper, making each print unique.
