This is a Top Hat made out of duct tape (100%) I used packing tape on this instructable, but I have made a couple out of just duct tape, so it is very possible to do it with just duct tape. Another thing, this is my first instructable, so bear with me. Thanks, and I hope that this helps you.
Step 1: Getting the supplies.
Ok. Let's get the supplies. What you will need is:
A duct tape roll (it can be colored, it's really your choice)
An X-Acto Knife or Scissors (I prefer the X-Acto Knife)
And a Cutting Board
