I've already lost track of how many Super Mario requests I've gotten but these were a little different in that they were shipped to Massachusetts.
I did some research of how other bloggers send cookies and meshed their tips together to come up with what was easiest for me.
I made parchment paper envelopes for each fondant topper and then wrapped each envelope in bubble wrap secured with tape. I piled the toppers in a small box and placed that small box in a larger box, using bubble wrap and plastic bags to cushion around all sides. Then I brought the box to FedEx and prayed they survived the trip across state lines.
I heard that they did! Whew!
