Turning Passion into Profit: How Do You Sell Your Papercrafts? Or anything Art Related as a beginner?

I'm passionate about papercraft, but I'm finding it challenging to turn my passion into a sustainable income. I make 3D Papercrafts. Also try to teach papercrafting on YT. Is anyone here successfully selling their papercraft creations? I'd love to hear about your experiences, especially when it comes to pricing, marketing, and finding customers. Any tips or advice would be a huge help!
