Harrison Jones created this fabulous green army man costume (which included a coating of green latex paint on his skin, yowch, suffer for your art!), and worked a full shift at a grocery store while so attired:
Harrison started by picking out the perfect green tarp, then taking it to the hardware store and having them color match a quart of semi-gloss interior latex paint. He then painted the air soft helmet, boots, and gun with several coats of the green paint. Next, he cut out cardboard in an oval shape, painted it green, and used duct tape in a loop to stick to his boots.
As for the uniform, he picked out a long-sleeve shirt and a pair of pants he was willing to sacrifice, and cut them both along the seams. Harrison then spread the chopped shirt and pants out on the tarp, pinned them to the tarp, and cut around the fabric, leaving about a half inch of extra tarp (the sleeves were done separately). He used duct tape to “sew” the tarp back together, leaving half of the tape’s sticky side exposed and putting it on the inside of the seam, and then connecting the matching part of the tarp, adjusting to the right fit.
