Nice T-shirt plan: and people can pick their preferred colour if white doesn't work for you!
I got a different t-shirt from zazzle recently, which I ordered on 2nd July, was produced by 7th July, and arrived yesterday - so there ought still to be time before the steddfod ...
I am worried by the pixelation warning though - does anyone know who made the SSIW logo?
If it would be possible to have access to the original file I'd be happy to have ago at figuring out how to export it at a higher resolution. Then it's quite straightforward for individuals to do a custom T-shirt on zazzle, using such a file.
Or perhaps whoever set up the zazzle SSIW 'shop' could re-upload a higher resolution version for the T-shirt in question (which is the one with nothing but just the logo on: "say something in Welsh" with a draig goch saying Welsh in a green speech bubble)?
