Abalone or Ahhh, Baloney!

My arms are killing me from winding all this wool! Starting the swatch for Abalone by Alice Starmore - I must be crazy to do this as my first fair isle type sweater...

But I love it! All these wonderful colors, with fantastic names like Bogbean, Calluna, Lapwing, Pebble Beach, and Wild orchid ... it even smells good! The swatch is coming along - my tension started out a bit loose - but has settled in to be right on. I need to decide a few things before starting -

Do a different cast on to prevent curling? Or do a couple rows of 1x1 ribbing? Do a cheap fair isle project to practice on? Or jump right in and do it?
