Your pattern piece doesn’t need to be flipped it’s your fabric or fusible needing to be facing the correct way. Example: if I cut out the letter A, then lay it facing me and I put fusible web on it, then it would be backwards when I ironed it in my block. But if I take that A and flip if facing down and put fusible on the back side, then flip it and iron it, I will be able to read the letter A cause it’s right side up. Does that help you understand it better? If not I can do a video showing examples. Let me know. Thanks for the question.
