Just go buy one of the 60 dollar pop up blinds.

How long are the Panels?

Sorry about that, they are 8'. I don't have them posted in the classifieds and don't need to sell them but am thinking, "what the heck?!?".

I use osb have had very good luck with it. Have on stand that is over 25 years old. But like any material that is out in the elements you have to do maintenance. Keep it painted with a good oil base paint (when built and then about every 3 to 4 years depending on enviroment you are in) I build blinds for a little extra money and have sold over 75 in the last couple of years. Use all different size of framing depending on what is wanted for weight and strength. you can use 2x2 or 2x4 deck screws or I use galv. ring shank siding nails work great (but you need to use a nail gun if nails beat it apart it you use a hammer. Make sure you caulk it real good then paint it. I will try to post some pics

Here are some blinds I built this year
the 7x7 has been covered with primos blind material
Most of the cost of a good stand is the hardware but if you go to ebay you can find most of hardware at a real good cost.

Remember you get out what you put in

how much it cost to build the 5x4

I have a little less than 200 in it

I wrap my tripods and ground blinds in 1" by 2" welded wire and weave branches and limbs through it. It doesn't take a lot of time or money and it blends in to the habitat you are hunting it. It will usually last the whole season.

Here are a couple of pics of this stand after being in the field for a year. This side faces SW and takes a beating from the sun. The other 3 sides aren't near as bad. The panels have not been painted. As for the structure that is great. Mr. Redneck builds a great stand that will last for years.
