I am guessing that these circles are put over the lid of a jar and then tied down with a cord or narrow ribbon??? for decoration? (In my opinion, it's a waste of good fabric, but my opinion was not asked for.)
If I guessed correctly, the pinked edges are adequate for that application.
LOL The fabric does make a pretty presentation. And that is what will sell it or not sell. It's more fun to have pretty then plain.
