This is a quick and easy sock pattern to keep your favorite 4-6 year old’s feet warm. It has a narrow heel to keep it from slipping or bunching and a simple ribbed leg.
There is a heel tutorial at http://knit1pearls2.wordpress.com/tutorials/

If you are substituting yarn take time to make a swatch. The fabric should be soft with some stretch to it. If it is stiff you may want to go up a size in needles.
