POD for wood/ceramic products? Feedback

I’m a college student and store owner doing various kinds of POD and also wood items.
I’m considering starting a POD-type business for wood and ceramic items. The idea is that sellers would be able to design and sell their own wood/ceramic products without having to make them themselves.
I’m trying to understand whether this is actually useful and what would make it viable for sellers.
I’d love to know:

  • Have you ever considered selling wood or ceramic products in your store?
  • What would make you hesitant to use this service?
  • What would you need to trust a supplier like me?
  • How would you want product design to work? Fully custom (you send idea, I send designs back), self-service editable template/tools, or a ready-made catalog?
  • Would you be more focused on brand new designs or selling designs/variants on designs that are already selling on Etsy etc.
  • I’d love to hear your feedback. Thanks so much.

Quick suggestion, nice idea.. you can go ahead, many merchant have this kind of store. Keep continue..
