A batch of 'acid-free' paper I bought online in 2020 just started yellowing on a project I finished last month.

I opened a custom poetry book I bound for a client to find the pages already browning at the edges, so maybe double-check your supplier's claims with a pH test strip before you commit to a big job.

Has anyone looked into whether the storage environment itself could be causing this? I had a similar thing happen and realized my studio lights were putting out way more UV than I thought, plus I keep my space pretty warm. The paper might have been fine when it left the supplier, but our own conditions can speed up that aging process a lot.

Yeah the "our own conditions" part is so real. I had a batch of prints go weird last year and it turned out my window AC unit was making the room way too humid. I got a cheap hygrometer and was shocked. Now I keep everything in flat files with acid free interleaving and moved my work table away from the window. It made a huge difference.
