we have a lqs that teaches an "heirloom quilt" class. the blocks are each made with embroidery and lace and fancy sttiching, generally done in whites or creams. so, to me, a new quilt like this would be what we are talking about. made for looking at and displaying but not for everyday use.
personally i make all my quilts to be used, just as many here have said. if they become true heirlooms after that, so be it. if they get used up and tossed out, so be it. once passed to the owner my work is done and i hope they love it like i do, but if not, then just do not tell me.
