Well, I bet some cat nip can help with used carpet. Either source works for me. I don’t have a set plan or dimensions, but do want a piece to wrap around a 4x4, about 2-3’ tall, and a piece (s) to wrap around the outsides of a base (not sure what size would stabilize it). If I have a few other scraps, I might just tack them to some wood panels and hang them on the wall near the door frames he’s been scratching as a substitute. Ultimately, I’ll let the carpet scraps determine a pattern.
Light table rug:
I also want to try making a small area rug by stitching a strip of sturdy cloth around the edge of a carpet scrap, using the industrial sewing machine at my work. I would need something approximately 5-6’ x 5-6’ to sit under a light table to protect the hardwood floor.
