Ok, so I am ready to (ugh) start HAND writing all these darn envelopes and realized my outside envelopes have a lovely black w/white flourish on the entire face of the flap. So I dont have a place to write the return address. It would not show up. Can Iwrite it below the flap? Also, um, would it be really tacky to print up a sticker if it was pretty? I know its worse to put it on the front...any suggestions?
