Most commonly, I dip-dye my flowers. I can also airbrush or hand paint them. Because each flower is unique, the colors may vary slightly from flower to flower. It can also vary from one type/style of flower to another.
There are all sorts of flower types. Some have thinner or thicker petals, some have wired petals so they are most “posable,” some still have bark on them, etc. The fun part of using sola wood flowers that still have bark on them is that the bark doesn’t usually take on color. So when I dip-dye, airbrush, or hand paint the flowers, the bark shows through. It adds a nice natural, or even rustic, feel to the flowers.
