A tray ... a few of your fav. things and flowers ... some greens ...lights ...
I was arranging the orchids in my silver tea pot ... the green glass looked nice with the silver ...along came some sand paper vine leaves ... and the tea light and candles and well ...
... a coffee table ... a console table ... your side unit ... a cozy nook ... and just about anywhere you decide ... I think you could try this arrangement ... complete with your diyas or candles ... I'm sure you too will feel the festive mood ...with some instant Diwali decor ...
If you liked this idea do share your thought with me ... would love to hear from you ... who knows two thoughts put together and we just may have another decor idea ... :)
