Hi! - For the mini-notepads, I gingerly, rip out one of the pages of the notebook, so I retained the holes as best I could. Then I traced where the holes were on a piece of cardstock that would match the front cover (so now, that was my template). Then I took the piece of cardstock I would use for my front cover and put pencil marks where the holes were. Then I took my paper piercer and pierced the holes through a mouse pad.
Next I cut a slit exactly vertical with my scissors. I put my atg tape right below the holes and then pushed the paper through the wire slits. MY Holes are much smaller than the holes on the notebook, so there's not much movement on my paper - I think that's why the slits seem unnoticeable (yah!).
my notebook cover does NOT fold all the way back though - so that's something to think about.
Hope that helps
