Moondance cable cap
It takes around 50 grams of super soft Moondance Shetland dk yarn to make this hat. It is available in 6 wonderful natural shades from Margie at www.moondancewools.com. You can buy kits from Margie to make up all my Moondance patterns.
You will need to be able to knit in the round and work cables in order to make this hat. The peak has no stiffener, so the hat is foldable and packable.
I've just added a photo tutorial describing the peak construction.
