Oh, truly a dilemma but fun! That's how I feel sometimes, too.
At some point either there will be a deadline, or I will feel guilty buying more fabric to 'audition', or I will get a brilliant idea, and I stop dithering and grab the cutter.
But there is always the next quilt, and I won't get to the next one if I don't make up my mind on this one. You know?
Does the fabric call to you at 3am when you are having 'power surges'?
