IMO,camo is best when it blends with the surrounds,a single duck has excellent eyesite,so you can imagine what a flock would be like.They don't see you from face on,unless coming low into decoys,they look down from above,so hide everything including yourself as best you can.Don't move until they in range and you are ready to get on them.If you don't want to buy to much in the way of camo,you can always buy a few lengths of hession from Aussie Disposals and paint it to match the areas you want to hunt.Either wear it as camo,make a hide from it or just drape it over yourself.
