Knitting is a fiber artform by which you can make a cardigan or socks or cap. Some of the results are attractive.
The knack is to take sticks and yarn and tweedle them in such a way that they form knots, etc., etc. It turns out Rhinos are not good at it. This may be the result of having only 3 digits per limb. We can usually triumph over such limitations, but knitting confounds Us.
This fact explains why you seldom see a tag inside a sweater saying “Knit by Rhino”.
