That looks great. Yes pothos doesn’t “grip” but will definitely climb if given an easy way. I’ve seen people letting them spread and hang across shelves in several houses. But the best one I ever saw was this lady who lived in an old run down place and had no shower curtain. She let the pothos grow and hang along the curtain rail, and the plant was massive. I don’t think I would have wanted to renovate that shower for as long as that plant lived, amazing how it worked out just right.
