These are mini art quilts based on "Milagros"
Milagros (also known as an ex-voto or dijes) are religious folk charms that are traditionally used for healing purposes and as votive offerings in Mexico, the southern United States, other areas of Latin America, as well as parts of the Iberian Peninsula. They are frequently attached onto altars, shrines, and sacred objects found in places of worship, and they are often purchased in churches, cathedrals or from street vendors.
They correspond almost exactly to the “tamata” used in the Eastern Orthodox Churches.
