Rattle can cammo ideas?

[One Shot]

I'll be keeping an eye on this thread.. I have a few ammo cans i'd like to do a camo job on. I suppose i better practice on something else first but hopefully this thread can give me some ideas.
Seems like finding the pattern is going to be the hard part

For a pattern I'll just put on a base color (tan for instance) and then grab a couple of handfuls of grass or leaves from the yard and scatter them over the gun and apply other colors (green and brown). The whole process takes about 20min.

Here's my buddy's boy shooting one of my rifles.
