Our “12 Days of Christmas” Holiday ornament series continues with the 2018 introduction of our Four Calling Birds Ornament. These four singing birds were carved first in clay and then mouth-blown in glass by old-world glass artisans in Poland. Hand-painted in creams, canary yellow, blue and ruby with their jeweled scarves and hats while perched on lush green branches. Embellished with fine glitter details and hand-set Swarovski crystals.
