Your products are bright and colorful, on-trend, and at a fine price point.
Your SEO is terrible.
This team:
https://www.etsy.com/teams/10713/etsy-relevancy-seo-and-stats has some great introductory threads (the light blue ones); esp. look at Etsy Relevancy Search Explained and How to do keyword research (you need both).
Also, you've only got 34 items; in your down time I'd also work on adding more.
