I actually just finished making a queen size one--made entirely on my serger! It is a series of squares and 4 patch of various blues from old jeans and I just serged it. Back and front are denim and no batting. It is heavy but I wanted for the spring/summer/fall in our trailer. I made matching pillow shams as well. Pretty straight forward actually. I followed a you tube video on how to make a serger quilt and just substituted the denim.
Good luck.
