Ok, you have put together some gorgeous original work and taken attractive photos of it. You work out the cost of materials used for each item plus your labour time. Now you know what to charge. That’s your selling price, plus postage. Research prices for similar items to ensure you’re not overpricing or under-pricing.
Make sure you read guides on setting up an Etsy store. It’s constant trial and error so you watch statistics to see what works, for example, good tags.
Once you’re confident, then complete the nitty gritty finance section and you can complete your shop site. Then GO!
Good luck! I’m setting up EveTactileArt so wish me luck too!
