Revealing mistake: When Iola's quilt shrinks in the dryer at the end of the episode, the individual squares do not shrink. Instead, there are simply fewer of them in each direction.
Visible crew/equipment: When Iola is walking across the stage to her podium for the debate, from her perspective you can see the edge of the set and some lights.
April Fools - S5-E18
Plot hole: As Mama tells Iola about the April Fools' jokes the family has played on her over the years, Iola expresses surprise. Considering Iola has been Mama's friend for years and is constantly at the Harper house, it seems impossible that Iola had never heard of any of the April Fools' pranks.
