I am a new knitter. I decided to learn to knit so that I could knit a blanket for my grandson. I have almost used up my first skein of yarn but I am not sure what I do to start using the next skein. My grandma (who usually crochets) thought that I should tie the ends together which would mean that I would have a small knot in the blanket but she wasn’t sure if that was the same procedure for knitting. Please help.
