I had a special request from a couple getting married at an aquarium for a for a wedding invitation with a shark on it! What could be cooler? This invitation comes with royal blue envelopes and a handwritten font - although if you don't care for that font, I've also done it with a more modern looking font as well. I was so inspired by the aquarium wedding idea that I created an Aquarium Wedding Pinterest Board as well!
