In reply to Allison S..

Thanks Allison. I'm sorry to hear that Flatty Works isn't making these any more. I'd always intended to pick another one up in a different color. They may still be available on the secondary market, and given how well they seem to be made, I wouldn't be surprised to see them pop up used from time to time.

If it helps, here's some of my original research when searching for form factors like this: https://hypothes.is/users/chrisaldrich?q=tag%3A%22index+card+pouch%22

I suspect that it wouldn't be hard to custom make one for yourself, then you'll have the benefit of being able to choose the color/material.

Thanks for the reminder about Object Pages. I'd tinkered with the idea a bit at one point and had meant to circle back on them. I too used to blow through Field Notes on a regular basis before converting to index cards.
