So, as a beginner woodbuther I watch sometimes related videos on YouTube, and one of categories it recommends to me is "furniture made from pallet wood"
When I do like how this stuff looks I am also curious - judging by video it takes A LOT of hours to process free garbage wood, so maybe after selling it gonna make very poor payment per hour
And here is the answer - https://youtu.be/kgAXUdyFDgQ
Foureyes Furniture - professional woodworker and more - made video where he builds couple of tables, one from scrape wood, another one from cheapest available (toplar [тополь]), sold on Etsy and calculated wage per hour
If this for mystical some reason is interesting for you, you know where to look
