In the first pattern I´ve accidentally written that the hats measure 20 inches, and 24 inches in diameter, when I mean that they measure 20 inches and 24 inches around the bottom edge!
On the second page in the written instructions for both the smaller size and the two larger sizes it says Decrease 16 stitches when it should say Decrease 12 stitches.
There is also a column too many in the chart.
The repeat should start right at the end of the dragon´s tail, the first column should be omitted.
The repeat for the small size should be 48 stitches, while the repeat for the larger sizes should be 45 stitches.
