Tinsel for Pony Customs?

[Tropical_Sunset]

What are some good places/brands to buy pony hair-sized tinsel, the same thickness used by Hasbro? I ordered some thinking I'd found the right size but it's way too thick.

In the UK we have a shop called Hobbycraft (you can order online yaiy) & if you look in its thread section there are some tinsel threads which appear to have the same texture & thickness as Pony tinsel. There's another tinsel thread here & I posted a picture of Xmas tree, who has green Hobbycraft tinsel thread through her mane & tail. The thread comes in a variety of colours including iridescent.

I'm sure other countries have their own craft shops with tinsel threads.

I use Sulky Sliver Metallic from Gütermann, which is available in the US as well https://www.sulky.com/catalog/sub/thread/metallic/sliver/

Did you look at etsy? Sometimes there're sellers with good tinsel either https://www.etsy.com/de/search?q=tinsel%20hair
