May one sew a piece of cloth onto the corner of a tallit (reinforcement), or sew around the tzitzit hole, using thread made of the same material as the tzitzit?

Synopsis

Rashi-based concern prohibits sewing with same-material thread within three fingerbreadths of the edge or around the tzitzit hole, lest thread be added to the tzitzit. The Rema extends this to any location where same-material thread is used. Wool tallitot are exempt in practice since sewing with wool is unusual.
