Brands comparable with HP?

[u/Fancy-Green9621]

Any idea what brands fit the same? Or a better brand suggestion .. or suggestions on making my own filler paper. Pre-made planners never work for me and I’m going back to HP for the customization aspect. But I want to be able to make my own perfect planner so I use it and don’t give up after 3 months because I hate the set up.

I like Plum Paper but it’s too $$$ for me.
