Yeah, it's done. I went to the City today to register for the business that I want to get started, basically selling my jewelry on Etsy and other sites. In Germany you need to register, especially as this is only my second employment, and I needed to notify my full-time employer as well. All done. The only thing left is a form that I need to fill out to give to the tax authorities, but that is a minor thing. So right now I am working on my Etsy page. I will let you know when it is up and running, so you can come to my store and show me some love ;-).
I am an official freelancer as of today. How exciting is this?
