I make my titles using Affinity Designer. I compose everything so they are right reading then I make copies of everything and flip them backwards. When I am ready to use one I cut it out and paint the printed side with paint and place it wet paint side down to what ever surface I am adhering it to and burnish it so all of it sticks to the surface. Before I add the paint I mark the back of the piece with an up arrow so I make sure it isn’t upside down when it is adhered to the surface. When it is completely dry I wet the paper with water and carefully rub all of the paper away revealing the right reading text.
