Im new to knitting and i just bought a Knifty Knitter, rectangular loom last night. I started a few minutes ago and im kinda doubting how it looks. Ive been pushing it down each time i pull the bottom string with the hook..but now, it looks like its starting to "form" at the bottom of the loom..except it looks stringy or loose. I dont want to continue with my knitting if, in the end my scarf will look too way loose. im not sure if im doing it right either..thanks, any advice would be helpful
