Team Green reveal ideas for after birth

So we are team Green 💚 which I have totally loved, However , it's driven all of our family crazy. We had to have numerous conversations with people asking if we could get scans to find out, have them put it in an envelope and let everyone else know except us etc.

So now that finding out is imminent (I'm 38+2) I want to make the reveal after birth a little more special than just a text saying boy or girl. I want to see their faces when they find out. I suppose its also slight revenge making them wait a little longer haha. All of our closest family are near enough to visit the hospital/house after the birth.

Does anyone have any ideas how to do the reveal? My baby brain isn't coming up with anything other than a coloured hat!
