I read most all of this thread and I am wondering if the question about false praise was because someone praised a quilt that the poster didn't think was good enough to deserve the praise. What I may see as praise worthy, she/he may think 'what is she talking about, that isn't very good'.
Maybe we know the story behind the quilt and realize that it is fantastic for the person to accomplish what they have, and the praise will encourage them to go on.
We all have our own taste and what one may think is false praise may be very genuine, if you are the one giving false praise- stop there are so many more people willing to give true encouraging praise that is welcomed.
