I dont believe in "false praise", however, I do believe in either not saying anything if you dont have something nice to say about the project. Usually, you can compliment SOMETHING. ALSO, beauty is in the eyes of the beholder. Many might think a quilt is "stunning" "love choice of colors" "fabulous" and others might find the same project "ugly" "hate the colors" etc. Find what you like about something or just dont comment.
