Printed or colored tyvek?

I'm looking for something like this. We make origami wallets for play money and thought it would be nice to have something that doesn't tear. So next we are going to recylce some mailers. But I think it will be fun to use something like this.

I had found another website with origami tyvek papers last year but can't figure out what it was now! For my purposes the paper doesn't have to be origami paper, just tyvek.

Thanks!

And I'm going to use our 5K race tags for projects too. DS is really excited about that!
