Tunisian crochet is incredibly easy. I learnt to do it when I was very young, because my mother was crafts-mad. She bought a large crochet hook in several parts that screwed together so that it was wide enough to crochet a rug. She saved up all of her old tights, and those of her friends, dyed them and cut them spirally and gave them to me to make rugs on which she and her friends would stand in their sculleries, to keep their feet warm. They paid me a shilling for each one. They would be dyed in mainly dark reds. The hook I used was a little thicker than the one in the video. I always meant to use several thicknesses of leftover wools to crochet a normal rug, but never got around to it.
