Thank you so much! This is great to see, as I am about to start a similar project since I have lots of paper products too. I currently compost them, but would love to get mushrooms for it before they head to the compost pile! I am about to start trying for the first time, and am wondering: Have you tried it without the shredder? I'm not sure I really want to invest in a cardboard shredder. Has anyone given it a try with wet mixed cardboard & paper (could include used tissues or even old clothes)?
