I have made many "Summer Quilts" - that's what my grandmother called them. I piece a top, make a backing and quilt the two together - no batting at all. I like to make them for high school seniors at church - they fold smaller than a regular quilt and are perfect for summers here in south Texas. Don't need many quilting lines - just enough to keep it all from shifting when it's washed. Light colored fabrics don't work very well for these - if you can see the backing through the fabric it doesn't look very good.
