In this video, we learn how to knit with two colors of yarn. Carry your yarn in the hand that you are most comfortable with. Then, don't tension it around your pinkie so you can control the yarn. Put your dominant color over your forefinger and the accent finger on the bottom of your forefinger. This way, you will be able to turn your hands to decide which color is going to go up and over the needle. This just takes some easy practice to get used to.
