Trunk or Treat

Every year for the past 3 years we have participated in our church's Trunk or Treat festivities. And, I must say, I am at a lost this year as to what we should do as far as decorating our "trunk" (we have a Suburban or we use my mom's minivan). So, knowing how creative all of you are... I thought perhaps it would be a great way to get some feedback from you! Any ideas? Please remember that they MUST be low-budget, preferably from common household things that really wouldn't require more than something I can pick up from around the home to put together! :))

Thinking caps on...
