Whenever I receive a new magazine in the mail (and I get a lot of them: Allure (where I'm a contributor), Vogue, Lucky, Entertainment Weekly, The Week, Seattle Magazine, Hallmark, and—don't ask—Seventeen), I immediately rip off the polybag and remove the blow-in and tip-in cards. They drive me, in a word, bananas. They fall out all over the floor, both at the newsstand and in my bathroom, they kill trees, and most importantly, they impede my reading pleasure.
Those thicker pieces of paper often are wedged between a gorgeous fashion spread or they are lodged between a compelling story. And when turning the pages, they cause my magazine to flop open to the spread where the blow-in card is, demanding that I pay attention to the subscription card. Grrr.
I don't have a fireplace to repurpose these as tinder. I liked this site's suggestions for blow-ins. I bet there are some craft opportunities for the paper. But the best thing I can do is to toss them into the recycling bin. They are dead to me.
