I learned this technique, which makes an image using the natural dyes in plants, from my college roommate Sarah. It’s great for making cards or simple botanical prints.
flowers or leaves to print
watercolor or other rough, acid-free paper
selection of hammers (including ball-peen or cross-peen, if possible)
hard work surface (cutting board, slab of wood, etc.)
tweezers or toothpicks
acrylic finishing spray (optional)
