I've not had any problems mailing decorated envelopes and do it fairly often. I've gotten some nice compliments from the ladies at the Post Office though, now if I could just convince them to have a Show!
Too bad you can't bribe Dennis to stay away with cookies, Michelle. I'm still thinking about you and hope things go well.
Here's another one I did with matching envelope. I think they really look better in person, but the scanner just won't pick up certain colors especially when I watercolor with them. I did hand-deliver this one to my upline this morning instead of mailing it.
