My mother also use to just call them summer quilts. It's great to know you can make whatever you want, and what works for you. :)

For baby quilts/receiving blankets I've often used just two layers of flannel.

For family quilts/throws our preference is often for just the pieced top and then a layer of fleece as the combination batting/backing all in one.

If a warmer quilt is desired I will frequently use the fleece for batting and then flannel for the backing.

Can you tell I love the snuggly softness of fleece and flannel? Lol!

Of course you can!

On the flip side, my daughter wanted me to make a quilt for a friend of hers that was always cold (she was a tiny li'l thing and ate like a horse... wish I could!) Anyway, she had a thick fluffy quilt from her grandma that wasn't warm enough, so I used batting, and fleece as the backing, and binding. Tied it. Yes it was bulky, but, she loved it! anything you can dream, you can do!

I've made several of them. I piece the top as I would for any quilt, then use flannel, minky, or fleece for the backing. I keep a small one on the back of my arm chair. It's a small quilt with flannel backing; not too thick to sit against, but just enough warmth so that it will keep my legs warm when DH turns the AC down low while we're watching a movie.

Cathedral Window quilts are quite heavy due to all the layers, so not a great choice to sleep under in hot climates.they are five layers of fabric minimum to make the design, so can be very warm.

I've heard them referred to as "coverlets" in years past. I found one in an antique store which had quilting done very simply, but no batting. Sounds like a great idea for those of us who love quilts but are post menopausal!

My sister is always warm. I made her a quilt for Christmas and used flannel (pre-washed!!) as a batting. Next time I think I'll use minky/flannel as suggested for a backing so only 2 layers. Unfortunately the FMQing doesn't show up as well, but in order to stay cool whatever is needed!!

How about using muslin for the batting like you would for a tablecloth

I recently I made two twin quilts for my grandson. He is really hot and does not use a blanket. I made the tops and then used flannel for the backs (he likes soft and fluffy). Then I used my long arm to quilt them. They turned out great. I did have to adjust the tension issues but just tighten it a little and everything worked out great. He loves his quilt. They were football and Houston Texans fabric.

For light weight quilts that we need here in hot SC Texas I use a wide interfacing that is light weight. A lady at a local quilt shop gave me this tip when we first moved here and I have made several with it and am very happy with the results.
