I totally dislike the show. Worse one ever.
Cheap, bad designs, and far from appealing.
Leave the walls alone. Just paint them, simple, keep it neutral. Let the buyer add their own touches. Some of it plain old gaudy. Who wants stuff nailed all over their walls and ceilings. Who is going to clean inbetween all those wood slats you nailed on the kitchen cabinet doors. The so called artistic touches, not even good. It makes the room worse.
I like to go thrifting and be creative with things I find. But there's a limit, and a way to use things with good taste.
Watch some of the other HGTV shows, and learn.
You'd save time and money by eliminating all the uneccessary "touches."
Thank You.
