Today, all things are too cheap. We need include the cost on the environment within the cost of our goods. Altering the price of goods is an extremely important mechanic to move us towards sustainability. It is ok for us to have fast fashion if it can be done in a non damaging way, if it cannot then we will have to learn to mend again.
I've been pitching the idea to any one who will listen. Many makerspaces already have stuff for textiles. Kids these are really into cosplay, crafts, homemade. Outside of a few STEM hubs, there's excess warehouse space AND untapped labor.
