I was just reading this and followed the link to knitter/shepherd Christien Meindertsma's site where she shows something of the process of knitting very large things with very bulky hand-felted yarn knit on very large needles. Kind of like this:
The feet on the rug and the artist look disproportionate, don't they? Clicking the car icon opens this series about felting the mega bulky yarn. Other icons link to knitted items for sale, archives, and vintage knitting instructions.
I wonder if Ann and Kay at Mason-Dixon Knitting and Christien are aware of each other's giant yarn rugs?
