Five things that seem obvious, but I never realised as a newbie knitter*

• There is more than one way to cast on

• You can knit flat on circular needles

• Yarn is more exciting than just acrylic

• Americans have a different system for sizing needles 

• Everything you need is on the internet

* I'm still a fairly new knitter, but despite my inexperience I'm pretty sure I'm past the total newbie stage!
