DIY Underwater Birthday Party Decorations

My daughter, Chesney, wants to be a marine biologist when she grows up. (I did too when I was her age.) So, for her 9th birthday, I decided to try a DIY underwater theme. I’ve included affiliate links where applicable to the products I used for these party themes.
