I've made a few table toppers. They have been for my large coffee table and generally just for decoration. I do place things - flowers; chips/dips; etc. on them so use the quilts for wood protection. In each case I have sandwiched with cotton batting and (hand) quilted. I do use W&N batting which is fairly thin. I'd probably do the same for my dining table but I'd rather just make a bed quilt if I'm making something that large!
