Pregnancy announcement ideas?

Michelle
So my husband and I are expecting our first little one and we thought it would be cute to make a pregnancy announcement that plays off of our citizenship since I'm Canadian and he's American and we're due anytime between Canada Day (July 1st) and Independence Day (July 4th). 
Does anyone have any cute ideas on wording or how to design the announcement? My cousin in law is currently playing around with some ideas that she'll show me later, but I wanted to get some feedback to maybe give to her as well :)
Thanks!
