I got the Cuben sample from the manufacture a wile back and it was free. They had sent me a single yard of a few types. However I read the company has sold to another textile manufacture so I'm not sure. You can however find it online from a few of fabric venders like OWF.

The red edging is made by bending a piece of 1" red gross grain then sewing. The holes are 1/4" and made with a tool that is hit with a hammer. You can find the tool and kit in most sewing shops. I happen to have a friend who has a press that will do a few size but for this 1/4" is fine and the kits don't cost much.
