This is flannel with bamboo/cotton batting that is about the density and consistency of flannel. I'd agree, it would be lighter and more comfortable without the batting. Instead of spring and fall, this is a winter quilt. Perhaps I should start calling it my 'ice fishing quilt'...
In future projects, I do plan to try a quilt without batting, and a cotton quilt with full size off-color flannel batting. I think the 'surprise' color in the fringe would look cool.
