My friend gave me his tallis with a set of new strings to tie. however, I was once told that its better not to remove tzitzis from a garment unless the strings actually need to be replaced.
Can I replace the strings on this tallis with the new thicker/nicer stings, even the the existing strings are mostly fine?
(only 1 sting on 1 corner is broken below the bottom knot with 1 inch still remaining)
Thank you!
