I'm part of the Boomerang swap - 35 DIFFERENT F8s and they all want to be something special. I actually wore out the binding in my It's OK book. (Gonna get it spiral bound). So yes, it is a normal quilter's affliction.
My rule: I pull about 3 patterns into closer consideration and select one from those. When I pick one, it is FINAL and barring any unforeseen issues I stick with it.
