I have reused thermocol plate for this painting ,which was a packing material for babycorns(Most vegetable/fruit vendors use such plates). For the ornaments i used designer,stone bindis.
I have used crimson red for the background & pearl metallic silver for outlining the plate & gold for outlining Ganesha. Actually the Ganesha was painted on an old piece of wedding card invitation & stuck on to the plate. I usually keep aside such invitation cards/sheets for recycling purposes
