I had asked on another post if buyers preferred the pieces "tidied up" - with a nice even edge - which I agree looks ever so much neater -
or
Whether they would like "the extra" left on.
Of the people that responded, most preferred to have "the extra" left on.
I decided - in many cases - to leave it on - and the buyer could tidy up the pieces if it bothered them.
I frequently cut fabric from the back side because it's easier to see the grain lines from the back.
