Show me your print shops?

Hi there, I hope this is alright.

I was wondering if anyone have any examples of custom print shops (whether it’s t-shirts, promo products, posters, etc.) operating on WordPress they’d be willing to share? I am specifically looking for WooCommerce shops, but viewing any shop type (Woo or not) would be great.

I am looking for the best way to handle extreme customization by the customer. Viewing your shops for inspiration would be great.

Appreciate it, thank you!
