I am often asked to customize a traditional wool tallit.  There are many ways to do that including new corners and/or a new atarah (neckband.)  Since the tzitzit are already tied, they must be removed in order to attach new corners.  If the tzitzit are of average quality, they are cut off, but some heavier and more expensive garments have thick wool tzitzit which I will un-tie and reuse! All of the tallitot on this page were modified with custom embroidery designs.
