Planning my own wedding

From the start, every decision about the ceremony, reception, and all the vendors have been made by me and my fiancé doesn’t seem to care. He isn’t helpful on deciding or picking out decor or ideas. I’ve came across some issues, but hoping this may give me some ideas, answers, tips, etc. I’m trying to possibly come up with a backdrop idea. I have no idea where to start with that. Our colors are coral, ivory, and aqua. I’m going to have few anchors around but not heavily. There’ll be small charms on the center pieces and a painted anchor at the favors table, as well as little anchors on our party favors. There really isn’t much of a theme, but I’ve been told the colors are beach so that’s why I added anchors. My fiancé is also a marine veteran. We’re going to have paper lanterns hanging up, rustic chest for cards, rustic box with wooden hearts for guest frames. I’m not sure what else I need to include as far as details to have some help in coming up with a back drop. Just ask away if I missed anything! Thanks
