many times charm packs are (coordinates) that go with a panal- or fabric line that has a main fabric and the charms- i've bought charms that pretty much cut off all of the pictures that were part of a main fabric- it is hard to tell what you will get when a yard of fabric is simply cut into 5" squares without taking design into consideration.
now i only look at charm packs in the lqs so i can fan them out & see what is there- unless they are just blenders/backgrounds.
you may be able to return your pack you are unhappy with-
