Four threads are folded through the corner hole, creating eight hanging strands. One of the eight serves as the shamash (winding thread).
Question 2
Can a non-Jew make tzitzit?
Tzitzit require lishmah — intent for the mitzvah. A non-Jew, not being obligated in the mitzvah, cannot provide this intent.
Question 3
Are tzitzit made from stolen threads valid?
Mitzvah haba'ah b'aveirah — a mitzvah achieved through sin — is invalid. Stolen threads produce invalid tzitzit.
Question 4
If one of the eight threads breaks after being properly attached, are the tzitzit still valid?
Threads that break after valid attachment: still kosher as long as sufficient length remains. The initial attachment was valid; partial breakage doesn't retroactively invalidate.
Question 5
Must the tzitzit threads match the garment material?
Material matching: the threads should match the garment material. A wool garment gets wool tzitzit, linen gets linen. Exception: techelet (blue) wool works on any garment.
