Just sharing my own opinion (you don't have to agree), but...
I joined Etsy 8 years ago in the spirit of the handmade movement.
I don't follow trends, I set trends.
Everything I design and make did not exist untill I made it up (yes, of course my ideas have inspired others since I started selling them).
So I never quite got the Etsy trending section. Why would we want to make what everyone else makes? Isn't that what all the large corporations do?
My advice: be creative, be unique!
