For the ones I usually make I cut out rings with the number of days on each ring with Mickey heads. Those all link into a large Mickey head. Then I let my DS's take turns cutting the rings. I have figured out a way that works for us that keeps them from fitting over whose day it is. My DS's are a year apart in age. Who ever has an odd age gets to cut off all the odd number days, and the DS with an even age cuts off the even days. Then the last ring that attaches all the others to the Mickey head says "We're on our way to the airport", and we all cut that as a family as we head out the door to the airport. I haven't had a chance to make one for our upcoming trip, or I would post a pic. I usually would have one made by now, but this is the first trip that the DS's didn't know about. This trip is a gift from Santa.
