I know top makes sense. But for some reason I've always done under, because that is what we did in my house growing up. For some reason I can't bring myself to change.
I'm happy to report that I somehow accidently installed a roll over the top, possibly subconsciously? And not I'm a convert.
You are, you just don’t realize it, yet. The more you try to consciously fight it, the more it will embed itself in your subconscious- you’ll notice how every TP roll is hung, now.
You’ll consciously hang rolls underhand, just to fight it, but that struggle will only reinforce how right it is to hang overhand. One day, 6-8 months from now, you’ll see this post and realize you’re a convert. We welcome you to the path.
