I have a few ground blinds on my property and they work great! The ground blinds I have are built of wood and are there year-round. The most common size I have are 4x4 square and 6 feet tall with a 2 foot overhang front and rear on the roof. I build them out of T-111 or Plywood and the bottom of my shooting windows are 40 inches from the ground. I make the windows 2 feet tall. I then can paint the outside in a camo pattern or wrap it in camo burlap etc… I also take limbs and place on the roof and one two of my ground blinds I even have made the roof into a big planter box and have planted wild grape vines, wild rose vines in it or kudzu. The vines then grow and help cover the stand blending it in. I have one ground blind that sits in kudzu and you can not even tell it is there even if your looking at it. I also always cover the windows with camo burlap and cut slits in it so you can see out it easily and be able to stick your gun through it. One other thing I always do is paint the inside a dark color such as black or line the inside with camo burlap also. I know this seems extreme but I hunt on private property and sometimes I feel you must get extreme or go the extra mile to get that big buck. I should also point out that my ground blinds are overlooking 3 to 5 acre food plots and I set them as far back in the woods as possible with a good shooting lane that will cover the whole food plot. I also use a tractor and disk an 8 foot wide walk way to the back on the ground blind. I always set up my stands (both ground, tower and ladder) where I enter and exit from the back and through cover so the deer wont see me as I approach. I have entered and left the stands many times while deer were in the food plots and they never knew I was there. If a deer ever makes me, I either move the stand or will not hunt it again that season. That’s just the way I am though and am fortunate enough to be able to hunt private land that I am in control of. Our season here begins Aug. 15th and runs through Jan. 1st so I also have small battery operated fans in my ground blinds to help keep me from sweating in the summer and I use small propane heaters in them as it gets colder. Sorry for the long response but hopefully you or somebody else might get an idea or two and they might be helpful!! Good luck!! CDH
