Exists and being able to handle the total volume of textiles are two very different things.

Prioritize self recycling. Especially if textile companies are now required to donate all their waste. The used stuff you donate is going to just add to the massive stream of textiles.

If you know how to make use of a large volume of textiles maybe it would be worth doing a project yourself.

The clothing charity system is completely over burned by the volume of textiles.

Honestly I would love to see some sort of decomodifying effort. Like all churches should have a free store. It's infuriating that they don't.
