Jeweler’s dilemma:  the words engraved inside tiny heart lockets are too small to read. The lines are so thin and shallow they can’t be filled with contrasting material. Paper isn’t water resistant and is too fragile. Is there a solution?   

Tada!  I discovered that parchment (animal skin, in this case from a sheep) with permanent black Sumi ink written using the tiniest crow quill pen met all the requirements. 

Except that each heart had to be tediously hand cut to fit inside the depression after it was lettered! 

Good thing I purchased the Optisight Magnifying visor at Paper & Ink Arts recently.
