Just one comment for you after looking at your shop. As per Etsy's transparency requirements for sellers you should disclose your handmade product's process to be completely in line with the Etsy terms of use.
That can mean different things depending on what you are actually making:
1. If you are printing blank T-shirts purchased from a supplier, you should at least mention this in your listing descriptions. It would be better if you show it with some pictures in your About page.
2. If you are sewing these T-shirts yourself as a collective (some workers under you), you should do the same as #1 and disclose your helpers (at least mention it in some way)
3. If you are designing the patterns only and working with a manufacturer for the T-shirts, you will need to submit a manufacturer application:
