Hi, I have actually used carpet remnents from my local hardward store (Home Depot). I have found that my cats seem to like short shag or plush carpets the best. I haven't really encouraged them to scratch on fabric (so there is no confusion with furniture or clothes).

I actually bought a nice corner scratching post off ebay and I know that it shouldn't be to difficult to make (I just don't have the tools). I have included a link for you to take a look at.
