Origami hats

Did you happen to buy Joan Sallas' hat book Hut Auf!, e.g. during the Mennorode 2004 convention? Or you have the Spanish version Origami Papiroflexia: CORROS DE PAPEL. Have you also tried to figure out the correct size of the paper for a hat that fits?

Thanks to Dennis Walker you can now calculate this very easily.
On his own website, Dennis has an Excel file that does these same calculations.

Enter the head circumference in centimeters in the field below. When you start entering the calculations will be displayed. If necessary, you can round to the nearest 0.5 centimeters.

Have fun!
