Where did we get this idea of creating a new garment specifically for tzitzis?
I believe that is what that Rov from the Vilna Gaon’s time did. He went around Europe convincing people to do this. Then Rav Chaim Volozhin tried to get shuls to say kedusha every Shabbos but his shul burned down twice so he stopped.
I forgot if I saw this in the back of the keser shem tov (?) in the back of the Nusach HaGra siddurs or in the back of the nefesh hachaim.
Then why dont we create tzitzis with a safety pin on the end so you can quickly attach it to any garment you need every day
Because of ta’aseh v’lo min ha’asuy. You need to make them, they can’t be pre-made
