Product review (5 stars): Stylish Modern Burner Covers
Available in the dollar store and other venues, most burner covers are shall we say a bit tacky, unless of course you like roosters or daisies on your range top.  My style is modern though and it didn't quite fit.
These are great!  I don't have any matching Corelle dinnerware to "coordinate" with, but they stand alone just fine.
I love them.
