Late answer sorry, I stopped Etsy because they have literally zero support and many problems.
However I resold whatever worked. Pins were a interesting business for example. Whatever people need to create things on their own goes well, even simple juwelry worked well.
Thing is it is very dishonest. 99% of the 'Handmade' products aren't Handmade. If you are ok with this fact and just want to compete with other Chinese resellers Etsy allows a huge Markup by their average pricing. Some markets like Pins are 99% resellers that picked Handmade as source. They have zero quality control.
Not sure what I should say, kinda easy money, very dishonest and ugly platform.
