You have to also consider StormDogOutdoors' reply a little misleading, because the deer in that area are already long-time acclimated to that "old fort".
Yes, people have argued during the rut there are times when a strange buck may see that and it won't be familiar to him, BUT when he sees other deer paying it no attention or are not concerned with it, he'll ignore it as well.
Most often when you erect something new that the deer are going to see, they'll keep an eye on it until they feel safe... which could be never. It's most always easier to hunt from quick-erect blinds from a rifle than a bow because deer afar are more comfortable with it. Deer that see it close-up are the ones who will be on high alert.
Erecting blinds where they are not in the deer's direct eye sight or line of travel is a prudent thing to consider.
I also know deer enough that with good camo clothes, being still and keeping an eye out, one can let deer get spooky-close just with this. So with that in mind, you don't have to build Fort Apache to be hidden. Now the irony in my words is that I like to build Fort Apache. LOL!
I use real natural materials. I like to pick a spot that is ideal, like what I referred to above, then poke brush and smaller trees vertical into the ground. I will also use side-cutters(pliers) and wire. I like to use #11 gauge annealed. Most your hardware stores have #16 gauge and that will work too. I use the wire to wrap and strengthen the brush where needed. I use trees/brush that is natural to that specific area. I take a knife and sharpen the butt end so I can poke them into the ground easier. I often take a piece of straight steel stock, like 3/8" or 1/2" and use it to pre-poke holes in the ground so the brush/limbs/debris go into the ground easier.
By the time I'm done, it will look natural, but be thick. I normally don't have horizontal things in the blind as I think it looks unnatural... unless of course I start with a spot that already has a large leaning tree into another. I built a special hunting stool to sit on that I can comfortably part my cheeks if I'm on a long sit. LOL!
What's real cool about the way I do it, is that the whole blind is hidden to the untrained eye and most likely won't be hunted by another hunter. Blind material, netting, etc, are things that attract other hunters. If you're in an area where other hunters are not a concern, then by all means, use those type materials to get the job done.
Be creative and imaginative, but remember, you want it to conceal yourself without drawing attention to your position and having it look natural will bring dividends your family will enjoy at the dinner table!
