Hiya!
I just started knitting a little over a week ago

I went to a class over at the local Michaels craft store and so it began. Anyway, I'm supposed to be knitting a hat. I did the cast on thing (it was 46 cast on) and then started to knit away. It started to get really huge when I wasn't paying enough attention to counting the stitches, so I decreased the stitches. What I'm wondering, though, is what am I doing wrong that I would be adding a stitch each time I'm switching over to the other needle? I'm supposed to go back in less than a week with 11 inches of knitting so I can finish my hat, but with these increases and decreases, I don't think so. Can someone help?
