Show HN: GPTShirt – Custom t-shirts powered by Nano Banana Pro

I have ideas for t-shirts all the time, and I found making them a pain - making a good design, volume minimums, long fulfillment times - so I rarely followed through.

I made this site to streamline things. You create and iterate on your design using text and references images. Once you save, you and your friends can order the t-shirts immediately. Fulfillment including shipping takes about a week.

People have been using it to create one off t-shirts of their friends, small group orders for in-jokes, and startup schwag.

Image generation and iteration is powered by Nano Banana Pro.
