I would agree STDs are important for DW. Have you guys talked about when the ring is coming? We were in the same situation, we had planned everything but no ring. All of our friends and family knew but still no ring. I felt silly sending out STDs without a ring. Well a month later the ring came so the STDs were sent out a week later ( I had them already printed, addressed, and stamped). But I think STDs give friends and family a chance to save money and prepare for your perfect day!
