The yarn is spinned of two threads: 100% light-grey Caucasian dog underfur (the first thread) and 100% sheep wool (the second thread).
Multifunctional usage of the item consists in that it can be placed in every place which needs massage and warming: knee, elbow, shoulder and even neck. Knitting - front stitch - is ideal for this purposes. It allows the item to stretch as lengthways, as widthways. As a result, knee-belts fit perfectly the exact place, and ties fix them that provides more warmth for the belts.
The knee-belts are knitted by double-hemstitch. Such method gives some advantages. Front hemstitch has a ribbing effect. That means knee-belts can be stretched as lengthways, as widthways.
The work doesn't have any signs of dog wool smell, as it has two stages of washing: firstly the yarn itself is washed, then the finished work goes washing. I don't use cutted wool, only underfur.
