My grandmothers both made "summer" quilts for me, both made them with no batting. One grandmother tied all her quilts so hers is tied; the other just did simple SITD to hold the layers together.
I still have both quilts; the one with SITD is about 30 years old; the tied one is about 25 years old. Both are in fantastic condition, despite me not really taking proper care of them in my younger years!
They both look just fine to me, and in fact I didn't even notice or think about the fact that they don't have batting until I became a quilter myself.
