For this donation quilt, I used fleece fabric for backing without batting.
It would be thick and warm quilt if thin batting was in between of the quilt top and the fleece, but I worried it may become too thick. I think it went well without batting. It is light and warm.
I got many snowman fabric pieces from my friend, so I made another smaller donation quilt with leftover from the first larger one.
This was quilted normally, which has normal cotton fabric and batting in between. I like this backing. It is flannel.
We are heading for summer though, I enjoyed snowman pattern :) I think it would be almost winter when they actually arrive the destination.
