Granddads are often wells of knowledge and teache us a lot. How can we repay them for everything? Giving them a bit of nice warm wool will do the trick. A pair of warm woolly socks, TV slippers or a warming kidney belt will certainly make them very happy. They will already be familiar with the great qualities of sheep's wool, even though over time, wool products have become quite rare on the market. So choose a special gift to remind them of the good old days.
