My Evening's Endeavor!

Today has been weird. I am tired from an eleven hour day yesterday--we visited our church's congregation in Crane, 3 hours east of here. I made chicken noodle soup for 2 of my sick friends, tried to make some bread which did NOT turn out well; it didn't help that I dropped one raised loaf as I was transferring it to the oven. Needless to say, none of this bread is leaving the house! Then, after a shopping trip and putting groceries away, I decided a knitting session whilst watching Harry Potter #1 was in order! I am ready for a Harry Potter movie fest--watching a movie a night will be fun. I love the music from these movies!

Question: Any ideas from the knitters in blipland how I might stop the cable from curling on the bottom edge of this sweater???
