I also love checking out what's new in the market for diyas and lamps...
Recently I picked up these small glass oil lamps. It's a small flower shaped glass container with enough space for two tablespoons of oil. On top of it goes a detachable metal flower-shaped wick holder!
Placing them on a terracotta plate and scattering white rose petals makes it a lovely center of interest.
Love the floral pattern the light and glass together create:-)
You could also place them on small traditional coasters and line them on your window-sill or entrance...
Here I have placed it on small framed 'Patachitra' painting.
