The Podruchnik (Russian: Подручник) is a small cushion, once used in prayer by all Russian Orthodox Christians in Old Russia, but currently only in use by the Old Believers. Measuring roughly 20cm by 20 cm, the Podruchnik takes the form of a small cushion, often with patchwork decoration which varies from region to region. Its sole function is to keep the worshipper's hands and face clean during the frequent prostrations that occur in church services, as it is felt that the fingers used to make the Sign of the Cross must remain clean during the prayers.
