Need advice on quilt?
 

So I am putting some baby quilts together the first one I'm going to back with white fabric and put binding between it the other one is going to have flannel on top and flannel on back. The one that has flannel on top and back should I use batting? I had quilt and I'm wondering if it

Usually quilts need batting but that is just my opinion.

I have batting I just didn't know it would make it too heavy

No batting makes a nice weight for a summer quilt, but if you want it to be used more I would add batting.

I recently finished a summer quilt with a cotton top and flannel backing (no batting), it's the perfect weight down here in the south and very cuddly, I'd think two layers of flannel would be plenty warm and anything but a thin poly batting might make it too heavy.

You could also use another layer of flannel for the 'batting' if you wanted it a bit heavier without too much weight.

Perhaps you could use the thinnest cotton batting as a compromise. It would be a nice weight. One of the problems with no batting is that the seams will show through to the front or backing. I also think it is less warm than polyester batting=even the lightest type. There is a product, Thermore, made for using in quilted clothing. I would think it just about the right weight.

I have found batting makes it much easier for me to quilt.
I made a table topper without batting and it was much harder to quilt.
I haven't made a quilt without batting and don't think I would. Just my opinion.

I used flannel as backing on a quilt and did not use batting. I have regretted it since. The quilt is too "flat" looking. There is no dimension to the quilting stitches.

My Grandma B made "summer quilts" that had just a top and back with no batting. They were tied.

My Mom made "lap quilts" that had a top, batting, and an old sheet for the middle. They were also tied.

Sometimes the warmth of two layers of flannel is "perfect".
