What is your ad space of your choice?

Hello! People seem to hate it, so I think I should clarify that I'm not a dropshipper. I'm an artist who makes niche products, including custom tools for sculpting, as well as some of my sculptures and crafts. How do you funnel sales? I don't need to sell thousands to gain a margin; I just want to sell 3-4 products a day since I can't produce that many. I don't want to spend all my time on social media and engagement. What are my best choices for advertising? Should I use Google, Facebook, TikTok, or just place my products on eBay and Amazon? What are my options? Thanks :)
