I was given a couple simple notebooks a couple decades ago that I immediately knew I would want to copy and I finally have! Mine are a little bigger and the originals didn’t have anything in the window, which was square. Here’s a little bit of how they’re put together.
I sent these as an extra small in the Galentine’s Swap. The last one was received today, so I can post 'em.
I might be addicted to these. I have already made another. It would be fun to see how much I could alter or tweak the basic structure.
