Has anyone ever used the very thin poly batting that is around 3.99 a yard? How good is this, or will it be best to use fleece for batting? Does the fleece hold up well inside the quilt? The warm and natural will cost me quite a bit due to the amount of quilts I plan to make. I do not want my quilts to be thick and puffy. Help I'm new to this. But I'm addicted to quilting and on a budget as most these days.
