Hi there, I'm fairly new to designing for print and I was hoping someone would know how to add bleed to a shape like the one below. The printer is requesting bleed of 3mm to add to the image, I have no idea how to add it to an image that's irregular like the one below. any help would be much appreciated.

Many thanks,

Robster
