I made one and just used a flannel-backed vinyl tablecloth. It was pretty easy to stitch. Like with all plastics, you cannot tear out your stitches because it will leave holes. So, make no mistakes! lol
It has held up quite well and it was very cheap. I just toss it in the washer for a regular cycle then in the dryer for about 5 minutes to loosen it up then I air dry it.
