i can't imagine that the work you put into sorting these 5" squares would be worth your time. i would sell a hunk of them for a certain price. to show what they generally look like, just fan them for the picture. you could also keep the same picture for everything and state that it is representative and that the content of the package will vary. perhaps you can sell them by weight, and figure out how much a pound or a yard is. sorting them would probably hurt your hands after awhile. another thought...how sure are you that the squares are cut accurately?
