I purchased chocolate brown envelopes for my invitations and rsvp cards. I have tried one through the mail and had no issue but my question is about addressing the envelopes. Because of the dark color I plan to use an ivory or gold pen for addressing. As I was thinking about it more I realized that I would then need to address both the mailing and return addresses on the invitation envelope and reply envelope which ends up being about 500 addresses all together. Is there a better way to do this? Does anyone have experience with printing on the wrap around label stickers? Just trying to save my hand a bit. Thanks.
