Knittinghelp.com has other great videos too. And a discussion board. I haven't used anything but the casting on and off videos though.
I've got one more scarf on needles - a more formal dressier scarf for Big T. It's a basket weave pattern and I'm enjoying watching it come together. I need to find something else to knit or somebody else who wants a scarf for my next project. Knitting is helping me focus in meetings and I'm very content knitting while I'm a passenger - in fact it makes me feel like I'm doing something productive too.
