When I have to cast on a loooot of stitches--like at the bottom of an in-the-round sweater, I use two skeins. One for the tail and one for the 'main' skein. When I'm done, I cut one to make it the tail and continue with the other one.

You can also use both ends (inside and outside) of the same ball if you don't have another handy.

Hmmm....that's a good idea. Of course I couldn't this time cuz I'm knitting double stranded and I think I'd wind up with skeins and yarn flying every which way. I get discombobulated very easily

Same comment here -- when using yarn double-stranded, instead of using two balls, you can use the inside and outside end of the same ball. You'll have to join in a new ball twice as often as you would if you were using two balls at a time, but it may be easier to handle one than two in the long run. Using this method, you'd only need two balls to do Ingrid's cast-on, and would only have one ball to contend with afterwards.
