How did you announce?

I’m overly stressed about announcing our pregnancy and how to do it. My husband and I have 6 parents. 8 grandparents. And 7 siblings. I don’t like clutter or anything that doesn’t have a purpose. I was thinking clothes or hats embroidered with “grandparent est 2025” or something but for all the important people it’s going to be expensive. I live 500 miles from my family and sending it in the mail each would open it at different times and I wouldn’t see their reaction until we go see them. But if we come out with presents they will all suspect we are and ruin the surprise. I want it to be a surprise, special because it’s going to be the first grandchild, great grandchild, etc. for all 6 sides of the family. What did you all do to make it special?
