Step 1: Understanding the Concept:
Some Indian embroideries began as a way to reuse old cloth. The question asks which one turns old used fabrics into an embroidered textile.
Step 2: Key Facts:
Kantha is the folk embroidery of West Bengal and Bangladesh.
Women layered old saris, dhotis and lungis, and held them together with fine running stitches.
The stitches form waves and motifs across the cloth. The result is a soft quilted piece used as a bed cover, wrap or shawl.
So Kantha gives new life to old fabrics.
Step 3: Why the other options are wrong.
Phulkari is worked on fresh, coarse khaddar cloth, not on old fabrics.
Chikankari is worked on new, fine white fabrics such as muslin.
Hand painting uses a brush and colour on fabric. It is not embroidery at all.
Final Answer:
Kantha embroidery transforms old used fabrics into an embroidered textile. This is option (B).
