MB 9: Those that are careful about the Mitzvah of Tzitzis - There is a Mitzvah to make a beautiful Tallis and beautiful Tzitzis. The same is true for all other Mitzvos that we should make them as beautiful as possible, as it says "This is my G-d and I will beautify Him" - [which the Rabbis explain as] "Become beautiful in front of Him with Mitzvos." However, it is forbidden to embroider phrases from the Torah in the Tallis, but nevertheless, if it was already embroidered it is permissible to make a blessing over it. Even on tapestries we don't give permission in advance to embroider words of Torah on them.
Binyamin Rudman sha-25
My, how time flies! We have now completed the Laws of Tzitzis, the fringes on the corners of our garments, and are now moving forward into the laws of Tefillin, the phylactories that men wear on their left arm and head during morning prayers. G-d willing, I should be a married man by the time we finish. To all those women getting bored out there: we will soon reach Halachos with practical implications for you!
Again, it is a great honor and pleasure to be working on this list, and to watch it grow at an astounding rate. I know that this would be impossible if not for the efforts of certain individuals from NY to Philadelphia, across the country and around the world, who have publicized this list to their friends; I would like to thank them again for their assistance. -- Yaakov Menken
