Growing up there were a few quilts at my Grannie's and I remember them being thick and heavy. That's what I want. So far I've used polyester batting and cotton batting. The first lapquilts I made were with polyester. One of them my Grannie used in the nursing home. It got washed probably 2x a week. Its so thin now....its still warm just thin. Ds' quilt that made last year I used cotton. Its washed 1x a week usually cause he drags it all over the house. Its warm but it feels thin. I'm ready to just start using blankets to get the thickness I want. Is there another batting that feels heavy? I guess its possible the quilts I remember had old blankets in them though. Sadly none of them survived.
