Guix logo re-use

[Benson Muite]

Hi,

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?  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?

Regards,
Benson
