I have a baby quilt that I am making I have the top all done and the backing is a flannel. I want it to be a very light quilt because the baby will be born in the end of july. is it okay you think to just put in basically a sheet? it is a fabric that I am not supper in love with and have not found a good use for. so i don't mind using it as a "batting". but do you think that it is okay to use quilt fabric for batting instead of something else? hope that this is clear as mud.
