Registration requirements for starting art business

I am looking to start a business with handmade decor items. Iteams would be crafted by myself. I would want to sell them online as well as offline. Which all registrations would be necessary starting a sole properitorship business of this kind.

Thanks

There are a lot of decor elements in my house, but over time I like to update it. I have so many custom made wall signs because you just can't imagine how great it is to get together in the living room and look at the handcrafted wooden wall signs just for you.
