Hajar's Gift

Hajar wondered when she saw the misery in the eyes of the lady from the portrait. She asked her about her sadness, then decided to help her, and promised to retrieve her smile. Hajar realized that Ms. Portraits sadness was related to some sack of fabric, which she gifted to her neighbor once. Hajar had no choice but to roam across the country, to prepare another sack and fill it with gifts. Keeping your promise is not easy, neither does gathering gifts! But the secret lies behind Hajars precious gift to Ms. Portrait, so what was it?
