I have a tallis katan. The garment and the tzitzis/strings are wool. It’s a v-neck design, and the neck opening is much deeper than I wanted.
Is there any issue with reducing the size of the neck opening using non-wool thread, i.e. generic thread that’s labelled “polyester”?
The same question would apply, I suppose, to repairing a tear in the garment.
Afaik it wont be a problem but ask your LOR
As always, check with your local rav/posek but I’m sure we can get a few of the resident CR poskim to provide a completely contrarian set of opinions on shatnes 101.
