From the North American Schachenmayr website:
The hat for skilled knitters who like the challenge of complicated patterns. In a very short time they can make an accessory that attracts admiring looks for two reasons. Firstly because the ingenious lacework creates a clever effect. And secondly because the hat reflects light in the dark. All thanks to the Schachenmayr Lumio Cotton yarn!

Finished dimensions:
Completed hat fits a head circumference of 19 5/8 to 21¼ inches (50 to 54 cm).
