Hello Helen, I am not sure if your message was for me or others.
From my experience (I also make crepe paper flower, but not often), the shipping is same. Most important for shipping origami items was make sure no room for the origami move (or as little as possible), I insert lot of tissue paper around the empty space, because tissue will fill up the space and won't damage the origami (specially the flower). In some case, I will wrap with clear gift wrap first, it will help to limited the movement while shipping.
Before I list, I usually will ship one to a out of town friend, so they can tell me if the shipping is good or not.
Hope it will help!
