The jute rope wrapped around one of the scratching posts was really getting worn. I ordered some new 1/4” rope, then cut off the top of the old rope. The bottom portion was still in decent shape, so I stapled the old end to the back of the post (which is actually two 2×4 boards.) I then stapled the new rope on and wrapped it tightly around the wood. I cut off some of the carpet so I could take the rope higher, because I have a couple long cats. I used a heavy duty stapler designed for furniture, with 1/2” staples.
