@Michelle Guldan That’s a different problem than stolen photos, and it’s a harder one. A watermark protects a picture. What got taken from you is the bundle: the concept, the series name, the look, and the fact you were consistent with it. Copyright does not protect an idea. It protects the actual posts, graphics, and copy you already made. Trademark can protect a distinctive series name if you are using it in the market as yours. For a small shop, I would do this, in order: Save the originals with dates you cannot argue with. Drive version history, the first live posts, the working files. A screenshot in your camera roll is not enough. Put the series name in writing as yours. ™ is fine while you decide if a real filing is worth it. File if that name is actually how people find you. Brand the work so a stranger would say what your husband said. Your name, your mark, your look. Subtle is fine. Invisible is not. Be more careful in rooms where the other person sells the same thing. You were generous. The lesson is not “never help.” It is do not hand someone the recipe and the plating in a competitor’s kitchen. Inspiration is “I like how she shows up every Tuesday.” Imitation is using your series name, your structure, and a look close enough that your husband called it without you saying a word. I am not a lawyer, and this is not legal advice. If the name and the look are the business, a trademark conversation on the series name is the one paid step I would consider. Everything else is you drawing a brighter line around what you already built.
