I took a bookbinding class on a whim at university, and it's still a hobby I enjoy. I would love to have a dedicated space for all the big equipment one day, but it's easy to make notebooks with just a bone folder, awl, needle, and thread.
Yeah I'm liking how 'simple' it is if you don't want to get super involved. Plus I've got a small woodshop so I can build myself some tools to help the process.
