These lovely wooden hearts are covered in small metal charms known as milagros. Milagro means “miracle” and these tiny religious charms depict legs, arms, hearts, breasts, ears, animals, people praying (just about anything really!) and are generally used to thank or request religious help for a specific problem. When they are not being used by an artisan, they are pinned on the clothing of a saint in Mexican churches or are attached to ribbons to be hung on a church or home altar. The milagros can be made of brass, pewter, pot metal, tin, and even silver. They are especially prevalent in Mexico and Peru but are also seen in Europe and can be known as "ex-votos."
