I do charge a $50 fee to return any additional flowers back to you. This is to cover the cost of my time to dry your whole bouquet, and packing materials to ensure the blooms are wrapped safely. If you choose to give up your remaining flowers they will be composted. I do not keep any remaining wedding flowers for other pieces I may create. My experimental pieces are made using flowers I've purchased, grown or have been gifted.
Dried flowers are incredibly fragile and transporting dried blooms isn't as simple as throwing them into a box or a bag. If the flowers bump into one another they can crumble and turn to dust. This is why each bloom needs to be wrapped separately in packing paper and then is stored inside a box with biodegradable packing peanuts (which you can later dissolve in water). Please note that additional dried flowers are just the blooms, they are not still on stems.
