I wasn't sure what to expect but I'm loving how these look!  They are 2x2 sheets that are lightweight and plastic!  Since they are so light I don't worry about how to install them!  I received two tubes of heavy duty glue type product that will hold them easily!  I have an area in mind to install!  They aren't too large so putting them in an area will make a pretty pattern and area of interest!  They look really nice!
