We have no place for a scratching post for our 2 cats so...I thought, why not put it on the wall. Carpet stapled to the wall and trim out with chair rail. Some cat nip spray and they love it. We had the carpet remnant and the chair rail so it cost $0.
Looks pretty easy to make, basket screwed to the top of a cat tree. I could use the big rope/twine that I purchased at Ace to go around the column. Then use the extra carpeting we have for the base & possibly around the round or square container we will use.
