One skein of this beautiful yarn is well enough for the hat to make.
The neckwarmer in the photo is not part of the pattern, it can be bought separately. Two skeins of the yarn is enough for both pieces.
Gauge is 6 rows and 14 stitches in double crochet, for a 10x10 cm patch.
The hat can be prepared in a few hours.
(May be prepared for children as well, if the band in crocheted shorter.)
