Those are badly slapped in photoshop. Searched for a hexagon pattern, removed the black lines and there you go.
I might do countries on request, if you post home, away and goalkeeper kits.
Maybe I need to get some patterns from PES mods (Specially for adidas kits)
I also have the adidas numbers, might search for Nike and Puma numbers, just in case you want some specific number
Does anyone have a link for the cool ass avatar maker?
