My blind camo process usually starts a week or so before the season when I cut down green cochia plants. I trim the plants so they are about 6 inches thick and flat on both sides. I slide these into the straps of my blind and zip tie them in. I cover the entire foot section of the blind, put a couple on each side and then one on behind the head. Cocia is found EVERYWHERE I hunt. They stay green for the early season which is great and then turn brown or grey for the regular season. When I hit the field, I just rake whatever crop residue is there and toss over the blind. The residue gets caught in the branches of the cochia and in about 5 minutes, my blind looks like a weed patch in the field. A guy can also stuff some residue under the cochia and it stays pretty well. For the doors, I find standing wheat or barley that has been left on the margins of a field and pull it up by the roots. I lace the long stuff into ONE door and arrange it so it covers both doors, then zip tie it to the straps. I find it's easier to just camo one door instead of both as they tend to wreck each other when you open and close the doors. This type of camp job will last the entire season and blends in with every situation I have hunted from flat soybean fields to sheet water edges and it's CHEAP. Good Luck!!
