Show me your birth announcement pictures like this.

I want to do birth announcements like this one, but I can't decide on which swaddles to use. I also want to incorporate somehow that these are our rainbow babies, but I don't want to use rainbow swaddles because we are keeping the sexes a secret until bith. So the birth announcement photos are doubling as the gender reveal and I want the swaddle to do that. I need ideas for both boy and girl. I'm just drawing a blank on this.
