I hand etched a loon on this bookmark made from a recycled ivory piano key measuring 7/16" x 3 1/4". The outline and shading are etched and inked with black india ink. Next I etch in all areas to be colored and apply permanent, pigmented inks with a fine brush. This ensures that all color is held fast for lasting use.
The final step is to seal it with 2 coats of archival wax to protect the intricate design and enhance the beauty of the ivory. The finished piece is water resistant but not waterproof.
