I'm a fairly new knitter. Mostly been knitting up scarves before this. I've now embarked on my first "not a scarf" project and am proud of it! I'm currently knitting the gusset on 10" bamboo needles and am going to run into a problem when it comes to knitting the bag itself and the straps. I need to go to the craft store and pick up some new needles. Which is better/easier; 14" bamboo straights or learning how to knit on circulars??
