PS That is a great idea — I’ll do it too!
I’m not just putting that on Christmas Cards..
I’m adding it to every piece of mail that goes out of my house...paid three bills today and posted that on the lower left hand side of envelope with a neat smiley sticker..
is it legal ...hell I don’t know, but I get envelopes with all types of messages on them...especially junk mail...Congress folks even had messages on their envelopes..that I instantly trash..so I guess I can do the same???? lol
