Putting the tzitzit strings through the corners

Hi,

Tzitzit have four strings looped through each corner, so that a total of eight string-ends hang down.

One may not put a single long string through the corner four times and then cut it to produce four separate strings; the strings must be unique from the start, such that putting them through the hole is the final act to create a valid set of tzitzit.

(Shulchan Aruch Orach Chaim 11:12-13)
