Nice tutorial, Shedrock. I build mine in a similar way only after setting the four white tops...maybe a little farther from side to side, I bend a gate panel and set it down between them...
So, you have a rectangle longer on the sides and shorter on the ends, with a wire mesh gate panel bent in between.
Cover that with burlap wool bags.
You dont have to cut shooting windows in the wire, at least on the sides. I cut one in each end.
The wool bags are cheap...well, they used to be. I dont know about know cause I have been using a pop up blind.
I have taken two Pope and Young antelop out of such a set up. Put it right at waters edge.
Once had 13 bucks come in together...the smart ones stayed on the far end of the line. Could have reached out and touched the youngest buck.
Good build along.
