DIY Blind material question

[Scoot]

I've made quite a few blinds in the past decade. I make them out of 2x4's, cattle panel, landscaping material (plastic and clothe-type), and plywood. These are not portable pop up blinds, but rather blinds I put in places where I expect to leave them in one spot for a long time. I've been looking at the Redneck blinds and I really like the looks of the those blinds! What I'd really like to be able to do is make the blinds just like I do, but with the material they use on the Redneck blinds. Anyone know if that material, or something like it, is available? It looks awesome!
Thanks,
Scott
