May one open the neckhole (beit ha'tzavar) of a garment that was tied by the launderer?
Synopsis
The Mechaber permits untying a launderer's knot at the neckhole but prohibits opening a new neckhole because it constitutes tikkun mana (completing a vessel). The Rema extends the prohibition to cases where a craftsman re-tied or re-stitched an already-opened neckhole.
