best place for large sheets of plastic

[Xist]

I thought that I had read that it was expensive at Home Depot, although I imagine they give a bulk discount. How much have you guys paid at sign wholesalers?

I may have mentioned somewhere, an old teacher ran for election and posted pictures on Facebook of his campaign signs. I thought that I could have put them to good use and I do not know who else would, besides an Ecomodder, I just felt bad that he lost the election.

Thanks for sharing this! I bookmarked it!

How many of you guys prototype with cardboard and how many with coroplast? I just wonder if it would be worth trying out cardboard before using coroplast. I found five 48"x96" sheets for $16.25 and $2.76 each for ten or more at Double Faced Corrugated, so if you could actually ever use ten sheets of coroplast, it might be worth going through cardboard first.

My last post was from a tablet, so I didn't give the full URL.
PolyMetal—High-density polyethylene (HDPE) with aluminum face and back.
PolyMetal Lite—High-density polyethylene (HDPE) with aluminum face.

I've experimented with rolling/braking/shearing samples; it's really stout. My local supplier is Multicraft Plastics. They quote $110 for a 4x8 sheet. It also come in 4x10 and 5x10' which might save buying a extra sheet for any given size project. So, 10 times as expensive as coroplat that's out of stock. Nudo have other products that might be of interest:
