Would like to use the Guix logo[0] modified to have a single color
without gradients to make an embroidered Polo-shirt[1]. Is this ok?
Of course :)
I don't know if you already adjusted the logo to your needs, but if you
haven't, maybe check the SVG icon in
https://gitlab.com/luis-felipe/guix-backgrounds. I did that one thinking partly
in embroidery but haven't actually tried it (don't know if the gaps are wide
enough).
It
is under a CC-BY-4.0 license. What is appropriate attribution on an
embroidered polo shirt? For example is the Guix name enough, should
CC-BY-4.0 and/or LFL Acevedo/sirgazil be added?
You don't have to comply with the attribution requirement if you are printing
the original logo or modified versions of it in your own clothes for personal
use (you don't have to credit me nor indicate the changes you made to the logo
anywhere in your clothes nor anywhere else).
If you plan to sell items with the original logo or modified versions of it,
you must give attribution as indicated in
https://creativecommons.org/licenses/by-sa/4.0/.
