ok..i'm getting frustrated. So i cast on stitches. Knit my first stitch over and put a marker on and then i'm knitting around and slowly the length of wool in the middle gets longer and longer...(the piece inbetween the needles). Then i have to keep pulling to the right to tighten the stitches..and if i don't i get these huge loops inbetween stitches...What is going on? what am i doing wrong?
