One thing that has been made relatively easy in the last decade or so is selling things online. I've talked about selling things that you have lying around on eBay and Amazon before but this is about creating things to be sold online. This might not necessarily be easy (though it can be) but hopefully it is something you find fun! Not only do these marketplaces have large names that you can reach more buyers because of their awareness, but if you do happen to make enough money off of it, taxes are made easy.
1. Open a Shop on Etsy

I created a shop a while ago to sell clocks made out of old records. I recently changed my shop because I don't have the storage space for that right now. I will be selling skirts that are made out of old ties. I am in the process of creating my first items but it is on hold because I am currently making masks because of the pandemic. Check out my shop here!

2. Self Publish a Book on Amazon

I created a few books for now that are journals, which is super easy to create but I want to start writing a few children's books which has always been a dream of mine. Check out my books here!

Costs vary but here's the formula: Fixed cost + (page count x per page cost) = printing cost

3. Design Fabric and Wallpaper on Spoonflower

You do have to proof each one which is a cost of $12-$35, depending on number of designs, to get started selling. But within the first day of having mine listed, I made $7 back! While it may be a large upfront cost, it's something you only have to make once and can profit off of for no extra work for years to come! I found I've really enjoyed creating designs and just do it for fun in my spare time. Check out my designs here.
Fees & Profit Amount:
Earn 10% of sales on your designs
Proof cost: 1-5 designs start at $12.00, 6-15 designs start at $20.00, 16-30 designs start at $35.00
