Go to an army/navy surplus store. Buy a canvass half shelter, might cost you $12. Tatter the ends (I used a pizza cutter), put a couple of holes in it, singe the holes with a lighter, a little weathering using a spray bottle with a combo of water and acrylic paint. Bam. Done under $20. You have the pride of having done it yourself, and the half shelter canvass is required for 501st approval. It was my very first build on my kit and am proud of it. Just take your time and look at galleries for screen accuracy. Good luck.
