So will the toilet paper rolls.

Squish them flat in one direction, then the other. I squish them flat to save space while I'm collecting them anyway.
Because I put the seedlings out pretty fast after sprouting, I cut the rolls in thirds. It saves potting soil and gives me more containers. If I had a grow light or better light than a tiny window (that *really* needs to be cleaned), it would be worth it to keep the plants inside longer and they would need more room for roots. But at just a couple of weeks old any more container height is just a waste.
Last year I made a bunch of the paper pots as well. Once you get into the rhythm of making them they go pretty fast. I didn't like how fragile they ended up, but they were more resistant to a mold issue.
