I had accomplished couple of sarees with fabric painting.
And the one shown here is actually the very first that i did, around 8 years ago. I did and gave to my mom she still have it with no damage.
I did the flower bunches as a set of blocks at different locations on the saree body and on the pallu. Here goes the saree view(the cloth is not pressed, pardon :) )
Here is another closeup of the flower bunch.
