Wall/sheeting advice for tree stand (NONWELDING Question)

[Reebz]

Attached is an old picture of a tree stand I made for the family. The picture is of the stand in the process. I want to change the walls height and make other changes. I could use the same roofing material for the walls but looking for alternatives. T1-11 is probably ok but I'm looking for light weight materials. Plastic sheeting? Any ideas?

Maybe corrugated plastic like "for sale/vote for" signs and such are made from. Same as a lot of backyard greenhouse kits. It's solid enough that it wouldn't be annoyingly loud in wind. It would just have to be affixed well enough that it wouldn't get torn off in heavy wind.

That a good idea.
