Hi ladies, FI and I are about to send them out, but I'm having a hard time deciding how I should address the envelopes. Our STD are postcards printed from VistaPrint and we got a simple white envelope to mail them in. It's a pic of us on the Austin sign and the info on the back. In my opinion it is pretty informal, but Austin fun. So please help me decide.... should I address them formally with Mr. and Mrs. John Doe. Or informally with John and Jane Doe? Everywhere I'm reading says not to include "and Family" on the front, but how should I address the children on a single envelope? Is it not needed for the STD and just for the wedding invitation? TIA!!
