Here is a free knit infinity scarf pattern from A Crafty House that will make you want to grab two skeins of super bulky yarn and size 19 knitting needles as fast as you can.
Ooooohhhh, that looks very soft and warm!
I know, and so simple! I love it when the instructions are so easy you don't even have to look at them. The rows are just K2, P1 for two rows and P for the third, and repeat.
