Looking for insporation

Thank you so much for your input! We genuinely appreciate you taking the time to write to us!

To start, when I say true blue, I mean basic primary color blue. I've attached our color palette a little farther down.
I've settled on a wisteria as our purple as it complements my pale skin well without washing me out or making me look too pink.Our colors have a specific meaning to us since we are Pagan: blue is a calming color, promoting feelings of ease (it's also my grooms favorite) purple is connected to spirituality in the Pagan beliefs, it's the color that represents one's self in the deepest meaning (typically a rich or royal purple but those can make me look weird in certain lighting). Silver (metallic) represents the Mother Goddess and her role in our lives. Aquamarine (teal) for us as water signs (I'm a Pisces and he's a Scorpio) and I like that it does add a brightness to a softer palette, though I'm not 100% settled on it and may swap it for another. Black is for protection in our beliefs and represents that no matter how dark it gets, we will always find each other. The colors matching the ring is because he picked it out with these things in mind. I hope that makes sense on why we chose these colors 😄
Though we may be having a wedding on Halloween it's not a Halloween wedding if that makes sense. We aren't doing a traditional wedding and instead are doing a handfasting. The date has a religious/spiritual significance to us. We're looking more at "bringing the stars to earth" kind of theme if that makes sense. Not nessecarial space themed but I want it to feel very ethereal.
I do like your idea for the loveseat! We're looking at having 50 people or less for guests, we'd like to keep it small and intimate (we don't have alot of people who want to attend anyways) so I'm not sure how many tables we're going to have but I also like the picture frame idea. I'm already thinking of all the photos I'll put in them after 😆.
For the linens and drapery I was generally looking at bolts of fabric that could be turned into garments (generally cotton or cotton blends... mabey an organza) as I like to make my own clothes and have a few friends that do as well. But I do like your idea of grabbing some swatches to carry around as I look for decor and things.
Decorations are generally going to be kept to a minimum I think except all the candles everywhere (I'm looking at battery operated for fire risk areas such as the aisle) as we don't want to over shadow the beauty of the nature around us. But I don't want to fall into "fall wedding fall theme" territory if that makes sense.
Something like these but with our colors to pop. Especially the first and last ones
