Mihrabs may appear in a variety of forms. Those on the prayer rugs of Anatolia, where the greatest number of these rugs have been made, are usually pointed and often have a step motif along their sides. Mihrabs on Persian rugs, however, are characteristically curvilinear and elegant, while those on Caucasian and Turkmen rugs are invariably rectilinear. Some prayer rugs have two or three mihrabs side by side and are known as “brothers' rugs.” Ṣaffs, or large prayer rugs used simultaneously by a large number of persons, are subdivided into many small compartments, each of which has a mihrab.

Prayer rugs are often decorated with religious symbols that serve the worshiper as aids to memory. Lamps, for example, recall the lamps of mosques, and the comb and water pitcher are reminders that the Muslim is required to wash his hands and comb his beard before prayer. Often Caucasian rugs also show stylized hands on both sides of the mihrab to indicate where the hands are placed during prayer.
