Using sola wood flowers

Hey y’all! I’ve decided to use sola wood flowers for my bouquets and arrangements and was hoping to get some advice. I’ve researched all the seller websites, dyeing techniques, stemming, etc, but was wondering if anyone had any input towards which flowers to get? I love the sola roses and the different varieties they have, but I’m also interested in including peonies and am open to ideas. I’ve played with the idea of getting the large 1,000 assortments, but am nervous about what kind of flowers they will have and not being able to return them if they’re not for me. Which flowers have you used? What looks best in a bouquet? Which were hard to work with? Any advice please!
