an exciting twist.

Turns out you can turn your envelopes 90° and then address them, and they will be delivered just fine with a single 37 cent stamp. To half of your intended recipients. The other half will receive either a) a letter from the Post Office claiming that they owe twelve cents, or b) nothing but a sheepish e-mail from you. It's a gamble I do not recommend.

I'm just glad I never took this chance on our homemade wedding invitations, thanks to seventeen separate bridal magazines advising me about the possible need for extra postage. Which it actually turned out wasn't necessary, because back then, I was clever in the engineer way (the way that works).
