In my younger days when I was a knitter (much to the irritation of Himself, who didn't like the clack lack of my needles when he was watching Murder One) I knitted a sweater from Rowan wool so thick that it stood up on its own. It was colossally heavy to wear, as it was not only very thick but also over-sized, I wish I had a photo of it. My mum thought it was very funny as she thought I had miscalculated. In fact it was my fashion statement. These days sweaters are either teeny-tiny doll-sized things or over-sized like your dad's. I was ahead of my time!
I now knit with bamboo needles, when I have them as they are much quieter and don't interrupt Himself's programmes.
