You can find signs made of corplast like political elections advertisement or go to a gas station and see if they have old beer advertising signs. If you don't mind paying for it, you can go to a sign printing store and buy a
4x8 sheet for about $18.I get mine from a sign shop. Cant remember how much, but I think it was about $18 for a 4x8 sheet. They might have scraps a lot cheaper if you just need a small piece.

The sigh shops are running a rip-off. I checked at one that wanted $24 for a 4x8 sheet.
If you are in or near a large city, look up plastic in the yellow pages. I'm just 5 miles from Regal Plastics in Fort Worth, TX - and a sheet of 4mil is $6.75. IIRC, Regal has outlets all over the US.
It that fails, then order on-line from these guys....
I've bought 3 4 x 8 sheets at a local sign shop for 11.00 sheet. It was about 3/16" , which I think is 4 mil. This guy even cut it
2 x 4 sheets for Pizza Box flyers.I like the idea of the poticians signs. LOL Some>I know some build their own planes out of materials like foam and coroplast.
