Tzitzit are specially knotted ritual fringes, or tassels, worn in antiquity by Israelites and today by observant Jews and Samaritans. Tzitzit are usually attached to the four corners of the tallit gadol, usually referred to simply as a tallit or tallis; and tallit katan. Through synecdoche, a tallit katan may be referred to as tzitzit.
Tzitzis
The all-white tzitzit is Ashkenazi. The blue and white tzitzit is knotted in the Sephardi style. Note the difference between the 7-8-11-13 scheme and uninterrupted windings (between the knots) on the Ashkenazi, vs. the 10-5-6-5 scheme and ridged winding on the Sephardi tzitzit.
