Rennagayle - it took two skeins for the scarf. I knit it on size 8's. It was not as wide as they said it should be, but it doesn't really matter. The hat will only take one skein, I think.
The cables were really easy - once I quit trying to force getting all three on before I slid the other three off. Now if I can only grab one before sliding off and holding the first three, that's what I do. Then I grab the other two and then switch them. It helped me to stop gritting my teeth so hard! I may knit a bit on the tight side.
