Sew on patches for boys clothes (Seaside BN21)

Hi,

I was wondering if anyone has any sew-on patches that could be used to cover up some small holes in clothes.

Particularly interested in themes such as aliens, rockets, footballs, guitars, video games, or more generally sports, music, space, technology, sci-fi, films, cartoons, etc.

Anything along those lines would be great, as long as it's not pink butterflies, flowers, hearts, etc.

Thanks for looking!
