I did the same with the previous version. I printed it out as a 36x48 color engineering print at Staples for like $12. I was hoping to stitch together the files this time to do something even nicer.
Honestly, the engineering print was nice enough and quite usable at the table. The stock is heavy enough to hold up over time as well. But again, I was trying to look into what it would take to get the very best quality possible.
Tyvek, it's really, really good. They offer it here at a place like Staples called OfficeWorks. Cost me $40 AUD for an A0 size print that came out really nice. Tyvek isn't only very durable and waterproof but apparently it takes the print much better than paper. It certainly looks amazing in person and because of the Tyvek texture, it has a bit of a "parchment" feel to it.
