Help! I am teaching myself how to knit via the internet
www.aokcorral.com How to Knit a Scarf) and I can't find an answer to my problem ANYWHERE on line. I get the cast on stitches onto the needle (using size 8 wooden needles) but when I actually start to knit I can only do a few stitches before the yarn (Medium 4) is so tight I can't get the needles through the loops anymore. I know I must be doing something wrong, or there is some trick to keeping the stitches loose, but I can't figure it out! (I can't believe it's not online anywhere- I imagine I'm not the first beginner who has had this problem). I've tried casting on really loose, and just about anything else I can think of. Any advice, tips, or tricks would be greatly appreciated! My goal is to someday knit myself and my cat matching cable knit sweaters...

I don't imagine I will ever get there if I can't even knit one row!
