What is the best way to package terra cotta pots for shipping? My first shipment of custom flowerpots suffered two fatalities - two of the pots were smashed on their way to their new home. So I'm replacing the two broken ones, but now I'm paranoid that *these* will break on their way, too. I currently have them wrapped in plastic bags with wadded up plastic bags between them and the box, and packing peanuts stuffed into every cranny. I have to come up with some efficient way of packing these things because I hope to sell lots of them eventually. Help?!?!
