Having just finished my taxes, I'm in a mood, so I will say that the paper that tax instructions are printed on is quite suitable, and Uncle Sam will mail you all you order. The manila envelopes they send them in make nice file folders too.
The recycled paper egg carton stuff is great, especially if you get the big ones in the 5 dozen package. You have to let them be out of the moist fridge a couple of days before you try to use them though, and you may fail your next cholesterol screening if you take it too far!
The worst, is having a catalyst stove that shouldn't have color print. There's maybe one page in a newspaper section that doesn't have color printing these days.
If you order something from Amazon, and it comes in a box eight sizes too big, with a bunch of that brown paper - bonanza!
Of course, it could also come in a huge box filled with a ton of styrofoam pellets - well, I have more packing for when I have to send something to someone I don't particularly like.
But, yeah, I was just perking up an almost dead fire, and I was ripping pages out of an old phone book.
