With two last names it doesn't matter how many times I put myself on the no-junk-mail list. Thopse credit card people are sneaky and always around the holidays I end up with 2 credit card offers a day. I came up with a cool idea to recycle those rely envelopes.
On the back of the reply envelope slowly separate the flaps from the back of the envelope. Then turn the entire envelope inside out and tape the flaps to the back of the envelope. If the envelope has a print on it, like mine, you can use labels to handwrite the To and From adresses or simply print the address from your computer on labels and secure.
