Decor and wedding centrepieces (faux flowers)

So I’m looking to try to save money by creating my own centrepieces for each of the tables at our wedding. I’ve come up with a couple of concept ideas and even made a prototype, however, I’m really unhappy with how the flowers look. In particular, I’m using orchids because it’s an important flower to me. I’ve tried hobby lobby, Michael’s, and even SHEIN but nothing really looks right. They look so fake and it’s really bringing me down. Does anybody have any recommendations for any faux flowers that actually look real and are easy to use for wedding centrepieces?
