I have a few large Blenko glass vases in vibrant jewel tones and want to display them on a floating shelf. I would like to illuminate the vases to give them a rich 'glow' ... what lights and configuration would be best? Rope lighting from behind? Puck lights from behind or below? Spotlights from above? Or one of those plexiglass illuminated shelves they use in bars to display liquor bottles? Help me see the light!
