Dried florals

I like to use the dried materials like sweet annie, german statice eucalyptus and some dried peonies and roses but when it comes to shipping them after a sale does anyone have a tip or way to keep pieces from crumbling off. I had someone complain about it because there was some dried materials in the bottom of the plastic bags that I put them in but I figure this is going to happen anywhere but she sent it back. I don't want this to happen again. I tried to spritz them before shipping but don't want to make them to soggy or lose their fragrance. here is a pic of one of the wreaths
