That's a great question!
Most of my inspiration these days comes from my personal needs. A friend and I have been working to build an off-grid farming space in Western NY that will be able to grow food all year. Our build is done with 100% upcycled and locally sourced materials, which has meant that we've needed to get a bit creative with the construction!
My #2 choice would have been YouTube, specifically the Primitive Skills and Primitive Technology pages. I don't generally recommend ANYTHING on legacy social media, but those two pages are an absolute treasure trove of useful information.
