Flowers can be whatever you want them to be. I leave collected bits and old stems to dry in the apple box I keep by my back door. Sometimes I put them together with new things blooming in the garden. What started as quick wreaths in the winter, I've realized has now become a five minute meditation for me. I don't what they will become, I let my mind wonder and my hands put them together. For me, doing flowers is a time to let go, relax and see where it takes me. Over the years, you get better and it becomes a muscle memory.
I think we tend to want to put parameters on things and visualize the end result. The part I enjoy the most, are the moments in between, thinking you're doing one thing, getting lost and finding something else. It's more the process than the end result. I also feel like this when I take pictures, which is why I tend to take a lot of photos of flowers.
