Welcome to the board and to the art of quilting. Just because you are not happy at the moment with the loft of batting used, doesn't mean you haven't made great accomplishments. Many of the quilters here have never made a king size quilt...especially being new to quilting. And so many of us make mistakes. Dust yourself off, be proud of what you have done already and move on to another project....next time you will know what to do!!
