Teaching Kitty Not to Scratch

Jipsy has been progressively destroying this (previously) rather nice foldout couch of Holland's. She has also begun to destroy a wicker chair of mine that was not expensive but I very much like. I have decided that something must be done. The internet says that you can spray furniture with "cat repellant" spray (I think it usually smells like citrus or citronella) or put double-sided tape on the furniture, because cats don't like things sticking to their paws. I'm going to go to the pet store this weekend to look for some spray or "Sticky Paws" tape. I'm also contemplating buying an ugly, crazy-cat-lady cat tower in the hopes that she will scratch that instead. In the meanwhile, the internet says that tin foil can be a temporary fix because cats don't like the sound tin foil makes. So here I am, with tin foil on my furniture. Did I also mention that we have blankets hung over our windows also? I'm wondering if I will ever have a presentable home again.
