Need gender reveal ideas ASAP!

I was firmly set on letting everyone be surprised at birth to see what gender my baby is-- even though my fiancé and I already know-- however the baby registry is causing me to miss out on some cute girl items my family could buy for us-- and they are so upset I won't tell them the gender lol!-- so I have changed my mind. I don't plan to have a reveal party I just want it to be something private for my fiancé and I to do to take a photo of for everyone else instead of me just saying "oh, it's a girl." Please, shower me with your ideas ❤️💚💙💜💛
