Is there any halacha about making Tzizit one corner at a time over a period of a number of days, or does all 4 corners have to be made all at one time? Is there a chumra like that? I might not have seen this halacha thats why im asking?Lchatchila or bedievid
Thank you for your question.
I am not aware of such a halacha. It is probable that the reason you haven’t seen such an idea is because it doesn’t exist!
