we all look at things differently. i have learned just from showing my quilts on this forum, that quilts i have made and maybe am not that crazy about, somebody else thinks they look great. i have seen quilts on exhibit that i thought weren't that pretty and somebody else thinks they are fine enough to win a ribbon.
a lot of it is a matter of taste. plus like someone pointed out there are problem children.
good thing there are no quilt police :P ;-) ;)
