This was like running nails on a chalkboard.
I mostly used a mangled paper clip and sometimes chimed in with a push pin. It felt awful, and it resulted in tearing through the pages. Basically, this was the least fun activity I've had to do to date. So I'm happy to get it out of the way so I can get on with scribbling, tearing, stickering, and otherwise dirtying my journal.
Note: I realize the goal is to destroy my journal with a reckless abandon, but I find I try my hardest to destroy it in the most organized ways I possibly can. This is, perhaps, something I need to work on.
