Thanks for the info on two colors!
Thank you for all the helpful suggestions. I had a little trouble understanding but i will check on you tube. I wanted to do a few rows of black then a thin gray stripe then continue in black almost all the way then do another stripe of gray and end with the same amount of black rows at the end. I am doing all knitting, no pattern, I'm not ready for the patterns they confuse the heck out of me. Thanks again everyone!!
