I was given a learn-to-knit kit as a gift and I have been trying to learn, but the instructions are very hard to understand, so I tried watching some of these videos. They helped me a little, but I'm just not sure if I am doing it right at all. I'm trying to knit an envelope purse, but I wondered, when you are knitting something, does it increase in length (like it almost falls of the needle) or width? Mine seemed to be increasing in both length and width for a while, but now it just seems to be becoming longer, and nowhere near envelope purse-shaped. Does anyone know what I could be doing wrong, or if it's supposed to be like that?
