For those that prefer to knit their own we offer the pattern version of the Dwarven Battle Bonnet
Printed in full colour with lots of photos to guide you through the knitting and assembly, this pattern includes both the variations on the pattern seen in the photo.
Worked in aran weight yarn with 5mm needles, you will be working flat and in the round, and the hat is fulled (felted slightly) after knitting to give a firm dense effect. You will need about 100g of yarn for the beard and about 60g for the helmet part.
We also offer this pattern as a download through our Ravelry pattern store if you prefer. http://www.ravelry.com/patterns/library/dwarven-battle-bonnet
