Well, I made it myself!
I spent several months scouring shops for vintage brooches, but I had the best luck on Etsy and eBay. I bought most of the brooches in lots and even used some old vintage earrings. I wired them to some floral wire, hot-glued the hell out of it, wrapped it up with florists' tape and tied a pretty ribbon around it. It was time-consuming but not really that difficult.
There are a lot of tutorials, but I put mine together by taking parts from two different tutorials: this one from Glamour This, and this one from my friend Ms. Awesome.
If you're looking for a unique bouquet that won't die after a couple of days, I highly recommend you do this. The project cost me, all in all, almost $200, but that's about what you'll pay for a bridal bouquet of fresh flowers, and you'll have your brooch bouquet forever.
