This is a pre-made item purchased on Amazon. It consists of fabric and three metal fittings. It's designed to be installed in the corner of a cage, etc. There are some places where the sewing thread is visible (see the second photo). I'm using a handmade cage, and it's not very tall, so I couldn't use it as shown in the example. That's why I'm selling it. (It seems you can cut and adjust the hanging parts.) I didn't actually use it, so there are no stains or scratches.
