I am not a particularly crafty person but when our shower needed a new liner I decided there had to be a non-vinyl solution. . . I considered fabric but was concerned about mold, didn't want any creepy finished fabric, and didn't want polyester. I decided to create my own Tyvek® shower curtain. Tyvek® is that material that the USPS priority mail bags are made out of. They are cradle to cradle silver certified. They are made partly from recycled plastic milk jugs and water bottles in a closed loop system.
I sewed two pieces together to make one wide and long enough piece. I folded one side over and sewed a section at the top. I thought I would need to add grommets but discovered a simple hole punch did the trick. There are no seams on any of the other 3 sides so water runs right off and nothing gets trapped. No fraying. About 6 weeks into the experiment and it is working really well. I think I will even be able to throw it in the washing machine if it needs freshening.
Unlike here in the USA where Frito-Lay caved to complaints of their compostable bag being too loud, the Canada division is standing their ground. Three CHEERS to our SunChip neighbors to the north. The company's campaign slogan is: "Our bag is loud, our bag is different, our bag is good for the environment, and our bag will remain on store shelves."
