I'm not sure what you mean by "plastic type". I might have to go have a look at Dollar Tree. Ordinary poster board might be okay indoors, though I'm not sure I see the point since it would flex as much as the mat. To keep them flat in a hot car you would need foam core, as Jan suggested. It stays rigid when hot and also would provide a little insulation. For a smaller mat, you might be able to find some free foam core after the next election when lots of people will have political signs to throw away. You could all your favorite candidate and offer to put a couple of signs in the yard, and then you won't have to scrounge for them after the election. But, of course, be honest and wait until it's over to use the signs for your intended purpose. LOL
Thanks for sharing this great idea, Jan! It's good to see you back here so soon. Hope it doesn't hurt to type!
