I picked this up down the street at a shop called International Silks and Woolens. It's a fabric/textile shop that caters to the film/theater industry. I actually went in to see if they had a woven wool similar to one of my grandfather's ties that I have (solid black medium/fine woven wool from Scotland). They didn't. They did point me to an area of silks that pretty much look like they were made for ties... Been contemplating trying to make a few (with all that spare time I've got haha). I was there near closing and had somewhere else to go, but oh god, they had all sorts of fabric that would make sick jackets
Anyway, I could go grab a bunch of them and mail them out... But it might make more sense to hunt them down at fabric shops on your own. Google "snag repair needle" and you'll find them. I'd imagine most bigger shops have something like that. I went in to get pins for pinning things to my mannequin, and also grabbed the snag needle, a thread trimmer, and a sweater/piling repair comb thingy. Figured those three would make for a good "flippers repair kit" that I could use to tune garments up before sending them out. Thread trimmer is great for cleaning up button holes and fraying tags... Overall more accurate than a scissor, and will stay sharper longer because you aren't using it to cut everything.
TL;DR- Google snag repair needle.
