What is "khayamiya"

Khayamiya (Arabic خيّامية Khayyāmiyah) is a type of decorative appliqué textile historically used to decorate tents across the Arab world. They are now primarily made in Cairo, Egypt, along a covered market known as the Street of the Tentmakers (Sharia al Khayamiya, or Souq Al-Khaymiya). This street is located immediately south of Bab Zuweila, and has been in continuous use since the Mamluk era.
