Trapline, it's great that you now realize you need more than just some panels set up 3 feet away from you & standing out as if using nothing at all. But, there's more that can be learned from that photo.
1. Always incorporate natural cover (even if it's not native to your immediate surroundings) because camo printed fabric & square shapes aren't natural.
2. If there's natural cover nearby, set up next to it. Don't build a blind on the most bare spot on a dike. Setting up next to natural cover will offer a better transition to your blind making it less obvious.
3. Build it high enough so that when you are sitting down you can be entirely in the shade. Shade is the best camo when you are limited on material. I build the south east to south west sides of the blind a little higher to help shade more of the interior of the blind.
4. Try to keep any open areas for getting in & out of the blind on the North side.
5. Angle material inward to help break up the black hole that is seen from above. It will provide more shade & give you something to hide under while birds work directly overhead. If angled inward, you'll have plenty of room for your blind bag, dog, etc, & a narrow top for better coverage. I don't understand why so many blinds are built so wide when hunting things that fly.
Sorry to get off on a tangent from panel blinds. That photo triggered me.
