Ok... I am a VERY beginner... I just learned to cast on two days ago.... I did the long-tailed cast on for hours and finally got it mastered. I'm now trying to learn the purl/knit stitches... the problem I'm having is that the more I try the tighter my stitches (or whatever from the cast-on) pull tighter and tighter... I'm not sure how to remedy this... or why it's doing it lol... HELP!
