I started an Etsy store 2 years ago. I only have about 6-7 items on it, and keep meaning to put more. But it’s almost paid off my GF. You can see it at: https://www.etsy.com/ca/shop/LevelInfinity
My sales this year tripled from last year. I have one item which I added (the land station) which is very popular.
I really like selling designs on it rather than the physical items. That means I don’t have to ship anything. It’s great. They account for about 1/4 of my sales.
I need to find the time to put more designs on it.
I would love to see your stores as well, just to see what kind of items people make.
