Best Artificial Rose Petals

I am using artificial rose petals for my wedding ceremony (real flowers are not permitted on the aisle) & to put on the guest tables during the reception. I need royal blue, silver, light blue, & white or ivory petals. Because they will be used where they can be seen up close, I’d like them to look as real as possible. Where should I get the petals from? I found some that looked good online, but when I got the samples, the colors weren’t what I wanted & they looked cheap and fake. Since most places don’t let you get samples and return policies vary, I’m looking for some expertise in where the best quality artificial rose petals are. Any help is appreciated!
