Started this Overkill tribute project last year (2016).
And it´s finished !!! :-)
The Overkill stripe patch (see my older pics) is selfmade by leather and a cutted backpatch, and so is the backpatch (was an "Electric Age" bp originally).
I cutted all out, done a green border and sewed it on.
The "O-bat" patches are made of leather, too.
The only "official" patches are the `Fuck You` bp and the small bat, all other embroidered patches I ordered in the internet by my wishes.
For me Overkill is more than a Thrash band...it´s a part of my life(style)...
