Prayer Bracelet - Some prayer necklaces come with a tassel

The Orthodox prayer necklace sometimes has a tassel on the end of the woven cross. These prayer necklaces have 100 or 300 knots and are often black but they do come in other colors. In Greece these type of prayer ropes are most common. The other countries only have the woven cross without the tassel on the end. These tassels are not found on prayer bracelets.
