We have two costumes, as I have two boys. The oldest Devon is a blue mailbox. We made this out of a box and used posterboard for the top. The rivets are simply dried glue drops and we spray painted the box. The front flap opens and there is a bad attached inside so that you can drop the candy right into the mailbox. My youngest son Dylan is sporting a box of popcorn. I simply tapered each side and hot glued it, then painted it all white. I then taped masking tape and painted red for the stripes. The popcorn it self is made from packing popcorn that I dabbed a little yellow paint and put one brown dot on the inside of each curved piece. I just hot glued the popcorn onto the box leaving a hole for his head. These were so much fun and very simple to make. My boys get so much positive attention when we do our own costumes.
