[londoncalling]

I wanted to start building my project z biker gang, and was wondering if anyone had recommendations for decals for the back of their jackets?
Many thanks...

Try Studio Miniatures. They do this sort of thing.

I used some left over WH40K skull decals left over from when the kids played it about 20 years or more ago.

I've also used wh40k decals.

you should have a try with nail art decals on ebay, they are pretty cheap and some halloween design could match (skulls etc)

I use them on my gaslands cars and with some cut they could fit on the back of your bikers easily

Flags of War have some gang colours in their street wars range

Greenstuff World have few interesting sets here: https://www.greenstuffworld.com/en/245-waterslide-decals

Take a look at Undead, Heraldry, and World on Fire.

Try ebay 'Nail art transfers', vast range and cheap as chips.
The only issue you might have is many of them are black images, so not great for going onto black biker jackets but worth a browse as there are hundreds to choose from.
