The Wimpel is a binding cloth used to hold a Torah scroll when not in use.  Traditionally, the wimpel is sewn using the swaddling cloth that is wrapped around a boy for his circumcision ceremony, or brit milah.  Hence, wimpels are often embroidered with the boy's name, date of birth, and date of circumcision.  According to a 16th century Ashkenazi custom, the child is brought to the synagogue three years later and, under the guidance of his father, wraps the wimpel around the Torah to symbolize his own binding to the scroll and its commandments.
