Nice thread as I just finished what I call a summer quilt...top=string quilt....backing=musling....sandwiched w/flannel. I am currently using it with a scrap quilt (that is sandwiched w/W&N) but I think w/the flannel it will still be too warm to use it during the summer as I'd hoped. So my next quilt I want to try, (as I have on hand) a flannel backed quilt with the top in reg.cotton material and nothing in between. I just hope the flannel still won't be too warm but we have the AC running and I think a flanned backed quilt might work out just fine. Good luck with however you decide to go but do let us know!!!!
