I use 80wt thread when making a wall hanging that I know will never be washed. It is especially good for making miniatures as it adds no bulk to the seam and you can get a really nice crisp fold if paper piecing. For a quilt that will be used on the bed...NO.
Also, would be good anywhere that you may want to use invisible thread. Great for raw edge applique.
