The site is fairly easy to make.
BUT
> Where is traffic coming from?
> Why not use etsy or a similar site?
> Will you be making the pieces or buying them from someone else? Can you keep up with demand if things do take off?
> Do you know about branding?
> Will the cost of producing all the pieces for customers to pick from kill your business? Shipping costs?

And most critical:
> Have you identified a target market that has $50/mo to spend on luxury products like this? Do you know how to cheaply and consistently get in front of them?

If not, your idea won't work. Putting a website up by itself is like a billboard in the desert.
