This shirt turned out great: the logo is large and easy to see.

Unfortunately, the printing process for these coasters doesn’t work properly for the Tailscale logo. As you can see from this photo, the gray dots are almost black and barely visible in normal light.

This shirt boasts a large Tailscale logo, which is easily recognizable from across the room. This logo works best on dark coloured fabrics, with black being the most iconic.
