Skratchie

I need to replace the tattering quilt on my bed (insert sobbing noises here) so we slept under the Ugly Quilt last night. It's too hot for the summertime, so I am trying to think of something I can do that will be "summer weight" ... anyone have any suggestions? I don't know if there's a lightweight batting or if I should use something else in the middle layer, but I'm open to suggestions!

Thanks.
