I finished the bathmat and it's warm and squishy and rather huge! In the end it weights 640 grammes, made up of three types of handspun held with various other leftovers, including sock yarn. At one point I had ten balls of wool attached to this project!
I love the way it looks and its really thick and squishy. It is just a touch large, but my experience is that they tend to felt down and shrink a little from wear, even if I don't throw it in a hot wash, witch I will do unhesitatingly if / when Tarragon pees on it.
