I didn't read all of these but the other day on the Fons and Porter show they discussed this and what they did was fantastic.
To make sure you don't loose your points they sewed 1/4 and when they got close to the point wandered just up past the point (I hope this makes sense) and then back into postion.
Then to get bulky seams to lay flat they clipped the seam(not all the way) in the bulky areas and then pressed those opposite directions.
