Ha. Just tried to upvote your comment and opened your profile instead. Still appreciate the information density, but I can see how it’s a pain for people who are more active here than I.
It might not be worth it to you, but you might try a slightly better quality printer paper. I’m using a generic store brand premium laser/inkjet paper (24 lb/90 gsm), and I’m not getting any bleed through or feathering. It costs more than normal printer paper, but handles ink well and goes on sale often.
I’m with you. Although I recently started writing a lot more than usual. I ended up buying a used wire binding machine. I’ve been making notebooks with nice printer paper and cardboard from cereal boxes recently. It’s worked surprisingly well, although I may get a better source of cover cardboard soon. The nice part is that I can make notebooks of any size and any paper (like watercolor paper for sketchbooks) with lots of pages. Much simpler than sewing the binding.
