I hate to say it, but Amazon Handmade is the only one stop shop I’ve found that can compete so far. I’m hoping that changes soon.
Depending on what you want there are specific marketplaces dealing in it. Aftcra tried to do American handcrafted stuff but they closed down recently. Most of the places are just T-shirt or other textile printing on demand or they give you the tools to make your own storefront without the cohesive “search everything we’ve got” format of Etsy.
That’s what I’ve found, which means I could be way the fuck off base because I’m just a drunk and I’m not passionate about handmade goods unless I happen to run across them locally.
