I think we've all done something like that. Glad you caught it in time. Good looking quilt.
PS, one of my guild sisters found one tree on her almost entirely quilted project was on its side. She drew in a tree stump, axe, and feet sticking out from under the tree. She named the quilt, "Where's Roger?" (her accident prone DH) Mistakes happen. I'm glad yours is fixable.
I think this is what I would have done too. Cute, fit right in didn't it and no need to take apart the quilt.
