There is no such thing as a time for making art, or for defining the growth of an artistic idea. Even defining the period for executing a piece of art is pretentious. We make a general, grand allusion to what we ‘think’ or incubating period. Art is unbound, unfettered. The idea comes by in a flicker, and many times flutters away like a big flirt.
Of utmost importance may be the visual experience of the work. It is usually safer to put a comma, to sign the piece of art even before its done. Really, Art is never done. It is handed over, and again, reinterpreted.
