On most Tallitot and Sephardi Tallitot Ketanot there are little knots on the bottom or side. What are they? Why are they there? What are their significance?
These knots help ensure that the front Tzitzises (which are holier) are not accidentally moved to the back.
The threads at the end of the garment are unfinished, so they get balled up and knotted. Is that for halachic reasons or practical ones, I have no idea.
