This is my "trashcan armor" that I made in one day for this simple halloween costume. What i was looking to make wasn't 501st quality, just something that looked and felt good, and was sturday enough to party with! 
I cut out the armor templates and traced the shapes to the trashcan. Then I used an exacto-knife to cut the shapes out and sandpaper to smooth the edges.
I spray painted all of the plates yellow first, then after they had dried, green on top but scraped some of the green away while it was still wet. (the weathering i did is not screen acurate at all).
The emblem on the right chest and the left shoulder were found online and i printed them out, then glued them on with a combination of white elmer's glue and water, then brushed the glue over them to seal them on the armor better.
The helmet was bought online :facepalm[ATTACH=full]79111[/ATTACH]
