Back when I was querying literary agents, a writing blog suggested using USPS Priority Mail envelopes for snail mail submissions because the packaging is free and they charge a flat rate no matter what you cram into them. So I picked up a bunch of envelopes and labels, and was fortunate enough to have a couple left over at the end of the process. Those remained tucked away at the bottom of a drawer, until today, when I used one of them to send a signed book contract to my agent! :)
I have one more envelope left… What should I do with it?
*With apologies to Maureen Johnson. I don’t remember how many envelopes I actually started with, but it was probably a lot.
