I bought a mass produced quilt about 15 years ago. It is still good and gets daily use.(my DD uses it all winter) You can tell the difference although not immediately as at first glance it looks just like the ones I make. It isn't the same though as look more closely and the pattern is printed on and the outline sewn around to make it look quilted. Although usable I should say that it has faded considerably so now looks kind of dull as well.
