Hi! I don't remember how I stumbled across your content but I'm loving it - thank you for sharing so much! I've been searching without luck and came back to ask: Have you ever seen anything similar to these Flatty Works cases in a 3x5 size? (They don't make the 4x6 anymore either, sadly. I may have to resort to procuring some duck canvas and make one.)

I'm in the process of moving my time & knowledge management (aside from a single shared calendar) to analog and I'm flying through Field Notes, but would like to proactively catalog permanent stuff on index cards in an ADHD-friendly Franken-Zettel-Memindex. I've been using Westenberg's Object Notes in my Field Notes for a couple of weeks and that's been really great, worth a look if you haven't heard of the concept. Anyway, a little water-resistant bag of this sort with a window in front seems like a perfect way to make a modern Memindex work on the go!
