This are instructions to make the Mad Hatter Hat from the new Tim Burton's Alice in Wonderland
Step 1: Cardboard Box
The size of the cardboard will be the measurement of your head, remember to add half to one extra inch of size so that it can fit over the wig.
How tall you want it is up to you, I made it the size of my head and a half, after this cut strips about an inch or 2 apart. DO NOT go all the way through the cardboard except on the bottom and top tabs that will be used to glue the top and the visor.
