I now hunt most of the time on the ground vs. treestand. Most times i just use what's natural and sit very still...it helps to have a larger based tree to lean against for comfort. I then pan with my head very slowly from side to side. I like to find an area where it ridges behind me with the bush and smaller based trees as backing. One key (imo) to concealment is outline break up, meaning don't sit on the top of a hill or ridge, get backed into it so your outline is soaked up into the large land mass. If you have basically flat land or treed areas and plan to hunt the location exclusively...then making a blind out of dead fall and pine balms is great. Both will be easily found in the immediate area and very natural...the bonus is pine balms have natural smell and cut down on wind pass through...so they are generally warmer than most blinds. To coin a fly fishing term "The key is to match the hatch". Meaning look natural and you'll be fine. Not only that it is much cheaper!
