What is the innovative medium used by Mrinalini Mukherjee's abstraction in Vanshri?

Hemp fibre

Answer: Hemp fibre
Mrinalini Mukherjee's works tilted more towards abstraction when she took up the innovative medium of hemp fibre.

The tension between internationalism (in which an artist could freely use the style of western modern trends like Cubism, Expressionism, Abstraction, etc.) and indigenous (in which artists turned to native arts) grew acute by the late 1970s. Sculptors like Amarnath Sehgal struck a balance between abstraction and figurative and created wiry sculptures as in Cries Unheard. In case of Mrinalini Mukherjee, her works tilted more towards abstraction when she took up the innovative medium of hemp fibre, as in Vanshri.
