It is a labour of love and the result of painstaking research. Chikankari - A Lucknawi Tradition by Paola Manfredi, an Italian, is a book that shows her close and long association with the craft. Lucknow’s chikankari is known across the world yet very little research or documentation has been done. Articles or features have appeared off and on but this book is amongst the first of its kind, which aims to document the vast treasure called Chikan. What makes the book extremely interesting is that unlike other books that tend to rely on second hand material, with exhaustive references and quotes, Paola Manfredi has filled her tome with passionate grass-roots level research. The narrative more in the nature of a personal journey, with all the quirks and street-smart practicality, makes the book refreshing. As Paola says in the book, it is not a scholarly or academic research but more of a documentation of the world of chikankari.

Paola questions the use of chikan as a word for embroidery, highlighting that it has a broader connotation encompassing haute couture, the fine art of making a garment, embroidering it and finishing it with finesse. She is no stranger to chikankari having worked with SEWA and several craftsmen. Her love for white on white embroidery also found a calling in chikan. Paola came to India to work in textile exports and as she says, “If you like textiles ... India is a heaven, an inexhaustible treasure trove.”
