Joval – Definiation
A joval is a large Turkish storage bag, usually about three by six feet and was used to store clothing or bedding. One surface may be pile but may also be flatweave. The bag opens on the long side, and often only the pile face has remained usable. They are woven as pairs but used singly. Alternate spellings one might also see are chuval, juval, tschoval and other similar terms are toushak and doshak.
