The yarn is spinned of two threads: 100% light-grey Caucasian dog underfur (the first thread) and sheep wool (the second thread).
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.
