Thinking of trying to sell without a selling platform? (Pics of my items for attn)

Okay so I have an etsy shop but I've always hated the fees of course. I've seen some people sell their products via Instagram or FB in a more direct seller to buyer way. Also brings up the fact that I would love to do different character theme pieces but I avoid it just due to etsy policies.

Has anyone tried this before? I feel like that could work better for me and give me a little more freedom on what I feel I could make to sell. Just looking for opinions:))
