I admit that I am mini obsessed, so don't be surprised if you see lots of mini posts going forward.
I love the Happy Planner List Pads, and was excited to see that they are punched with the same number of holes as the mini requires. When I tried a page in the mini, it did hang over the bottom, but here is a tiny hack that works perfectly. Just trim a 1/4 inch from the bottom of the list pad page. To make it look “official”, I used a 5mm corner rounder after trimming. That's it, folks!
