announcing to family

Tabitha
So besides my parents I only really talk to my one cousin and his wife and kids on my side of the family...we are only 7 weeks and 1 day but we are going to their house tomorrow and I want to be able to tell them in person.
we are telling my husbands family after our first scan when we will be with them all (very big Brazilian family!!) I am so excited to tell them! 
Even though my family is really small I wanted to still make it special. I know it is really early but god forbid anything went wrong I know they would be a good support system. So I am not worried about sharing the news early.  We have a whole thing planned out for my husbands family but nothing for mine.
Anyone have any ideas on how to tell my cousin and his family we are expecting?? Everything I see online seems so big and since it's only the four of them it seems silly to do something big. 
Thanks so much in advance !
