Black on Black Retzuos

Black and Black Retzuoth, must one be makpid it shoud not turn (shiny side over)? and if yes what’s with Fasting.

Answer:

Concerning the retzuos that dangle down from the Shel Rosh, and that are wrapped around the arm, the reason why we are careful that they should not turn over is because of zeh E-li ve-anvahu — it is matter of beautifying the mitzvah, and not a strict halachah.

For black on black retzuos there is less of a need to ensure that they don’t flip over, because the difference between the sides is slight.

Best wishes.
