Revealing mistake: The sheets hanging on line are brand new just out of the packet. They still have creases in them.
Continuity mistake: About a third of the way into the film Ree tells Ashlee, who is playing on a trampoline with two rocking horses, to "bring Brownie and Cupcake and come in." In the first shot Ashlee is riding Brownie, and Cupcake, a pink horse, is lying on its side. In the next shot as she is getting off the trampoline, she is riding Cupcake and it's Brownie who is lying on its own.
