For this pattern I have used Scheepjes Stone Washed yarn in colours:
Brown Agate (Dark Brown) Beryl (Yellow) small amount New Jade (Light Green) Malachite (Dark Green) Rose Quartz (Pink) small amount Black cotton for embordering mouth and eye brows Yellow Jasper (Gold/Yellow) For the crown
Of course you can use any yarn you wish, just make sure you use the correct size hook the yarn calls for.
9mm Black safety eyes
3.5mm hook
