Merino sheep wool is white only after processing. In the paddock it is a dusty brown, often laden with prickles. Shearing is done once a year.
Similar to the ‘grazing sheep’ , I started construction with a re-bar back bone and legs on which I hung cut pieces of corrugated iron secured with pop rivets about every 4-5 cms apart. On the base of each foot is a pipe fitting to stabilize the sheep in the mulch. Obviously the contented expression comes from a full belly of my lawn!
