I don,'t know if I made myself clear or not. I have never knit a hat on a circular needle before so I am not sure if the length of the cable makes a difference. The pattern is for a toddler hat using a 5 mm needle which is 24 inches. I have a size 5 mm which is 29 inches. I would like to know if this would do or should I go out andbuy one which is 24 inches long.
