Hello! First off, this is a super old question (it went into drafts instead of queue!) and by now you would have received your Annoy a Postman.. sorry! Anyway, I don’t really have much experience with Crown Mill paper other than the ones I have, which is a ‘cream’ paper. I don’t know much about cotton paper, vellum seems expensive, but I do know laid papers are very pretty, and quite nice to write on. I know that Michael Sull loves laid paper. As for the third question, I don’t particularly care for the Ivory ink, but the Bright White McCaffrey’s is pretty spectacular! My first bottle didn’t do very well and I had to do that frankenink if you remember, but the recent bottles are pretty great right out of the jar. I just wish they sell 4oz bottles of those because I go through em like water! One word of caution though, never shake the bottle or you'll end up with a mess. Just stir it with a coffee stirrer. Bleedproof white is still my most opaque go-to homie, but I gotta say I have been using the former a lot more these days..
