This scratching post is made from an unused IKEA shelf, FLOR tile samples (snagged from Design Within Reach), carpet tacks and a liberal application of catnip.
This could be easily done with many objects around your home. From that old picture frame in your attic, to the leftover trim pieces in your garage; don't be afraid to use what you already have. Happy constructing!
Thanks Philissa (an avid AT reader as well!), great idea!
